- Network type of Temperature and humidity sensor
- Provide output RS485 for host collection;
Ø Belong to precision network type of temperature and humidity sensor, can set communication address 0-255 and baud rate 1200-9200bps;
Ø Take standard test, with high precision and accuracy of the calibration process function, low-power, high stability;
Ø Provide output RS485 for host collection;
Ø Communication protocol uses standard MODBUS agreement
Ø RS485 bus can withstand 4 KV lightning and keep well.
Ø Flame retardant insulation fiber shell, adapt the rapid terminals, safe and reliable;
Ø Extensive use, equipped with temperature and humidity probe for measure the temperature and humidity of all kinds of pipeline and special occasions.
Installation and application guidelines:
Ø Fixed the sensor on the wall;
Ø After electrify, the sensor have self-check for 1 seconds, later into normal working condition;
Ø Keys set: press button “3” (set) and keep for about three seconds to enter setting state, press “3” again to switch communication baud rate setting and address setting; then press “2”(adjust) to change the value, with the way of circulatory increase; the last, press “1”(confirm), means confirm, save the setting and back to normal work state.
Ø The default value of communication baud rate is 9600bps, address is 1.
Ø Request of other special temperature and humidity sensor, please contact with suppliers;
Ø The power supply can't miss access to output terminal, or may cause permanent damage to the sensor.
Ø If appear abnormal, please check power and connectivity carefully , if can't remove the faults, please inform maintenance personnel.
Ø Without professional guidance, open the sensor for operation and maintenance can destroy product performance.
Ø If you need detailed communication protocols, please contact with suppliers.
