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.
Ukusetha nokufaka
Ukufakwa Kwebhethri:
- 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.
- Vala ikhava yengxenye yebhethri ngokuphephile.
Ukukhethwa Kwesiteshi:
- 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.
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.
Ukubekwa:
- 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.

Imiyalelo yokusebenza
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.
Isibonisi Sokufunda:
- The sensor's digital display shows the current temperature and humidity readings.
- These readings are also transmitted wirelessly to your paired SMARTRO main unit.
Isondlo
Ukushintshwa Kwebhethri:
- When the battery indicator on the sensor or main unit shows low power, replace both AA batteries promptly.
- Ensure proper polarity during installation.
Ukuhlanza:
- Sula ingaphandle lenzwa ngomshini othambile, damp indwangu. Ungazisebenzisi izinto zokuhlanza ezilumayo noma ucwilise ucingo emanzini.
Ukuvikelwa Kwemvelo:
- Keep the sensor away from direct sunlight and heavy rain to prevent damage and ensure accurate readings.
