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.
Configuración e instalación
Instalación da batería:
- 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.
- Pecha a tapa do compartimento da batería de forma segura.
Selección de canles:
- Locate the 1 to 3 Channel Switch inside the battery compartment (refer to Figure 2).
