Presenting: Sensor +! overview

Presenting: Sensor +! is an optional Purah Pad upgrade quest centered on Robbie’s research at the Hateno Village Research Lab.

Presenting: Sensor +! is a side adventure in The Legend of Zelda: Tears of the Kingdom. It becomes available after the initial Shrine Sensor has been unlocked, and it begins when Link speaks with Robbie at the Hateno Village Research Lab. The quest’s purpose is to expand the usefulness of the Purah Pad rather than to resolve a major regional story conflict.

Robbie asks Link to gather data on five different types of monsters. The quest therefore uses the Hyrule Compendium as part of its progression: the required information comes from registering the relevant monster types, after which Robbie can use the collected research to perform the upgrade. The source material does not identify particular monster names, so the quest should be approached as a compendium-data task rather than a fixed list of named encounters.

After the upgrade is active, the Sensor can track any item, monster, or object registered in the Hyrule Compendium. While Link is moving, the tool supplies audio and visual feedback, and its proximity meter helps indicate the direction of the selected target. The Sensor also communicates whether the target is above or below Link, making it useful for searching across different elevations and for repeatedly locating materials needed for gear upgrades.

Requirements

The known prerequisite is access to the initial Shrine Sensor. The quest then requires monster research before Robbie will perform the upgrade.

  • RequiredInitial Shrine SensorUnlock the initial Shrine Sensor before attempting to begin Presenting: Sensor +!.
  • RequiredAccess to Hateno Village Research LabRobbie is the quest contact, and the quest is initiated by speaking with him at the lab.
  • RequiredFive monster types registered as researchGather data on five different types of monsters so Robbie has the information needed for the upgrade.
  • OptionalA target worth trackingAfter completion, registering an item, monster, or object in the Hyrule Compendium allows it to be selected for Sensor tracking.

Objectives

  1. Speak to Robbie at the Hateno Village Research LabThis starts the side adventure after the initial Shrine Sensor has been unlocked.
  2. Gather data on five different types of monstersUse monster encounters and Hyrule Compendium registration to satisfy Robbie’s research request.
  3. Ask Robbie to perform the Purah Pad upgradeReturn to the researcher after the monster-data requirement is complete.
  4. Select a registered target for the upgraded SensorThe completed tool can search for a registered item, monster, or object.

Walkthrough

  1. 01

    Make the initial Shrine Sensor available

    Unlock the initial Shrine Sensor

    Before this side adventure can begin, make sure the initial Shrine Sensor has been unlocked. The supplied information does not identify the preceding quest or the exact unlock sequence, so use the Purah Pad’s available research functions as the confirmation that this prerequisite is complete.

    Location: Purah Pad progression

    TipIf Robbie does not offer the quest, check whether the initial Shrine Sensor is unlocked before looking for a different quest trigger.

  2. 02

    Find Robbie

    Travel to the Hateno Village Research Lab

    Go to the Hateno Village Research Lab and find Robbie. Presenting: Sensor +! starts through conversation with him there, not through selecting a target in the Sensor interface.

    Location: Hateno Village Research Lab

    Watch outThe source material does not provide a precise route to the lab or a separate alternate starting location.

  3. 03

    Begin the monster-data assignment

    Accept Robbie’s research request

    Speak with Robbie and begin the side adventure. His request is to gather information on five different types of monsters, so the central progression requirement is research data rather than a single named boss or a fixed combat arena.

    Location: Hateno Village Research Lab

    Checkpoint
  4. 04

    Complete Robbie’s five-type research requirement

    Gather data on five different monster types

    Encounter and register data for five different monster types through the Hyrule Compendium. The supplied facts do not name the required species, specify an order, or state that the five types must be defeated in one continuous outing.

    Location: Hyrule

    TipTreat the task as a registration objective: the important result is having data on five different monster types available for Robbie’s research.

  5. 05

    Have Robbie upgrade the Purah Pad

    Return to Robbie after the research is complete

    Once the five monster types have been recorded, return to Robbie at the Hateno Village Research Lab. Ask him to perform the upgrade rather than leaving after the research requirement is satisfied.

    Location: Hateno Village Research Lab

    Checkpoint
  6. 06

    Confirm the upgraded tracking function

    Use the expanded Sensor

    After Robbie performs the upgrade, choose a target that is registered in the Hyrule Compendium. The enhanced Sensor then supplies audio and visual cues while Link moves, with the proximity meter indicating direction and additional feedback showing whether the target is above or below.

    Location: Hyrule

    TipRegister the materials, monsters, or objects you expect to search for repeatedly so the upgrade supports future exploration and gear-upgrade gathering.

Mission mechanics

Presenting: Sensor +! links the Purah Pad’s Sensor to the Hyrule Compendium. The important distinction is that the upgraded tool does not merely detect a general category: it can track an individual registered item, monster, or object selected by the player. This makes the quest’s research requirement directly connected to the reward’s long-term utility.

The Sensor communicates through both sound and visuals. Its chime is movement-dependent, so a stationary player should not treat the absence of a chime as proof that the target is elsewhere. The proximity meter adds directional information, helping narrow the search instead of replacing the need to move through the environment.

Elevation is part of the guidance system. The tool indicates whether the selected target is above or below Link’s current position, which is especially useful when a search crosses different levels of the world. The supplied facts do not define an exact range, signal frequency, or interface iconography, so those details are omitted.

The upgrade is particularly useful for repeat searches. Once a desired material or other target has been registered, the player can use the Sensor to help locate it during later exploration, including searches connected to gear-upgrade needs.

What works and what does not

Strengths

  • It expands tracking beyond the initial Shrine Sensor’s role by supporting registered items, monsters, and objects.
  • The proximity meter provides directional assistance instead of relying only on an audio cue.
  • Above-and-below feedback helps when the target and player are on different elevations.
  • It is valuable for repeated material searches and for finding resources associated with gear upgrades.

Weaknesses

  • The target must be registered in the Hyrule Compendium before it can be selected for tracking.
  • The Sensor chimes only while the player is moving, so standing still does not produce the same audio feedback.
  • The quest’s research requirement asks for five different monster types, which may require seeking out several separate monster encounters.
  • The supplied information does not establish exact detection range, signal timing, or a complete list of the five monster types.

Best uses

  • Marking materials that are repeatedly needed for gear upgrades.
  • Searching for a registered monster type during resource or research runs.
  • Using directional and vertical feedback to narrow searches across Hyrule’s varied terrain.

Checklist

  • Unlock the initial Shrine SensorRequired before Robbie can start this upgrade quest.
  • Speak to Robbie at the Hateno Village Research LabThis is the known quest-start interaction.
  • Gather data on five different monster typesThe source does not provide the species names or a required order.
  • Return to Robbie after completing the researchAsk him to perform the Purah Pad upgrade.
  • Register useful future targets in the Hyrule CompendiumOptional preparation for using the upgraded Sensor efficiently.Optional
  • Select a registered target and move while searchingThe Sensor’s chime is active while the player is in motion.

Rewards

  • Purah Pad Sensor upgrade
    Robbie upgrades the Purah Pad after the player gathers data on five different monster types.
  • Expanded Sensor tracking
    The active upgrade allows tracking of any item, monster, or object registered in the Hyrule Compendium.
  • Directional and elevation feedback
    The Sensor provides audio and visual cues, a proximity meter for direction, and information about whether the target is above or below the player.

Aftermath

Turn the upgrade into a search tool

After Robbie completes the modification, register the items, monsters, and objects you expect to seek repeatedly. The expanded Sensor is most useful when supporting resource farming and locating materials needed for gear upgrades, rather than being treated as a one-time quest reward.

Trivia

  • The quest’s reward changes the Sensor from its initial Shrine-focused function into a Hyrule Compendium-based tracking tool.
  • The five-monster research requirement is separate from the later choice of a target to track; the upgraded Sensor can follow registered items, monsters, or objects.
  • The Sensor combines sound, visual feedback, directional proximity information, and above-or-below guidance rather than relying on a single signal.
