PA1115 MODBUS (RS-485) Temperature and Light Sensor


The measured temperature is sent directly in °C or °F by a Modbus protocol expressed as both FLOAT32 and INT16 data types. The sensor sends the measured value according to Modbus/RTU/ASCII question-answer protocol.
The thermal sensor uses an element with an accuracy of ± 0.5°C for temperature measuring.
A red LED indicates that temperature measuring is in progress.
