The SMARTRO Wireless Remote Sensor (SENSOR92) is a compact, battery-powered device designed to transmit outdoor or indoor environmental data to a compatible main unit. It features a digital display showing current temperature (in °C or °F) and humidity (%RH). The sensor is equipped with a wall-mount hole and a table stand for versatile placement.

Setup and Installation

  1. Battery Installation:

    • Open the battery compartment cover on the back of the sensor (refer to Figure 2).
    • Insert two (2) AA batteries, ensuring correct polarity (+ and -). Batteries are not included.
    • Close the battery compartment cover securely.

  2. Channel Selection:

    • Locate the 1 to 3 Channel Switch inside the battery compartment (refer to Figure 2).
    • Select a channel (1, 2, or 3) for the sensor. If you are using multiple sensors, ensure each sensor is set to a different channel.

  3. Pairing with Main Unit:

    • Place the sensor within close proximity to your SMARTRO main unit (e.g., SC91 or SC62).
    • On the sensor, press the "TX" button (Transmit button) located inside the battery compartment (refer to Figure 2). This will send a signal to the main unit.
    • Follow the pairing instructions for your specific SMARTRO main unit to establish a connection. The main unit should display the sensor's readings.

  4. Placement:

    • The sensor can be placed on a flat surface using its integrated stand or mounted on a wall using the wall-mount hole.
    • For outdoor use, choose a location that is protected from direct sunlight and heavy rain to ensure accuracy and longevity. The transmission range is up to 200ft/60m in an open area.

Operating Instructions

  • Temperature Unit Selection (°C/°F):

    • To switch between Celsius (°C) and Fahrenheit (°F), open the battery compartment cover.
    • Press the "°C/°F" selection button located inside the compartment (refer to Figure 2). The display will update accordingly.

  • Reading Display:

    • The sensor's digital display shows the current temperature and humidity readings.
    • These readings are also transmitted wirelessly to your paired SMARTRO main unit.

Maintenance

  • Battery Replacement:

    • When the battery indicator on the sensor or main unit shows low power, replace both AA batteries promptly.
    • Ensure proper polarity during installation.

  • Cleaning:

    • Wipe the sensor's exterior with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.

  • Environmental Protection:

    • Keep the sensor away from direct sunlight and heavy rain to prevent damage and ensure accurate readings.

Troubleshooting

ProblemPossible CauseSolution
No readings on main unit / Sensor display blank.
  • Low or dead batteries.
  • Incorrect battery polarity.
  • Sensor not paired with main unit.
  • Sensor out of range.
  • Interference.
  • Replace batteries with new AA batteries.
  • Check battery orientation.
  • Press the "TX" button on the sensor and re-pair with the main unit.
  • Move sensor closer to the main unit.
  • Relocate sensor away from electronic devices that may cause interference.
Inaccurate temperature/humidity readings.
  • Sensor exposed to direct sunlight or moisture.
  • Sensor placed near heat sources or vents.
  • Sensor not calibrated (not user-adjustable).
  • Relocate sensor to a shaded, well-ventilated area, protected from rain.
  • Move sensor away from heat/cold sources.
  • If readings persist, contact customer support.
Main unit not receiving signal from sensor.
  • Sensor channel not matching main unit.
  • Obstructions between sensor and main unit.
  • Verify the channel switch setting on the sensor matches the selected channel on the main unit.
  • Minimize walls, large metal objects, or other obstructions between the sensor and main unit.
