Product Description

RS485 Modbus RTU Protocol SHT30 Humidity Temperature Transmitter

Votesen VTH300-T Humidity and Temperature Transmitter has excellent reliability, high precision, and interchangeability. It adopts the 100% original import Sensirion industrial-grade high-precision temperature and humidity sensor. The default temperature and humidity sensor of this transmitter are SHT30, you can customize other types of SHT Sensirion chip according to your needs, such as SHT20, SHT21, SHT25, SHT31, and SHT35.

 

Its RS485 hardware interface adopts the lightning protection design. The protocol layer is the standard industrial Modbus RTU protocol. When you connect the RS485 hardware interface, the sensor will output the temperature and humidity through the serial port adjustment tool. The RS485 communication distance can be up to 1000 meters. The three major parts of the transmitter: input power supply, temperature & humidity measurement unit, and signal output are completely isolated. Thus our product is more safe and reliable, beautiful in appearance, and easy to install.
