RS485 temperature and humidity sensor, with the United States and Switzerland for temperature and humidity sensors and RS485 bus technology, based on industrial MODBUS-RTU protocol to achieve low-cost temperature and humidity status of the online monitoring of the practical integration of sensors,
This sensor can be applied to
(1) SMT industry temperature and humidity data monitoring
(2) temperature and humidity data monitoring of electronic equipment factory
(3) cold storage temperature and humidity monitoring
(4) warehouse temperature and humidity monitoring
(5) GMP pharmaceutical monitoring system
(6) environmental temperature and humidity monitoring
(7) temperature and humidity monitoring of telecommunication room
(8) Hotel temperature and humidity monitoring
(9) file room temperature humidity monitoring
(10) intelligent home temperature and humidity monitoring. Other needs to monitor the various occasions such as temperature and humidity.
In order to facilitate the engineering network and industrial applications, the sensor uses the MODBUS-RTU communication protocol, which is widely used in industry, to support the development of two times. Users only need to use any serial communication software based on our communication protocol to realize the query and setting of sensor data.

System schemeRS485 sensor built-in RS485 interface converter, through the RS485 bus networking, you can extend the communication distance up to 1200 meters, can be an effective solution to the most simple connection distance is too short.
Sensor Typical temperature and humidity monitoring and control RS485 network, each sensor has a node number, a small system, you can place 1-35 RS485 sensor. Because each sensor uses a wide battery-powered, so the whole system can be bus-powered solutions.Communication protocol
This product uses the standard MODBUS-RTU agreement, may directly with each kind of configuration software direct connection use
