DR4421 Temperature Humidity Transmitter
DR4421 Temperature Humidity Transmitter
DR4421 is a temperature humidity sensor, which uses a high sensitivity Industrial thermometer to detect the temperature and humidity concentration in the current environment, and transmits it to the host computer or server through RS485 or 4-20mA. The temperature humidity sensor provide power reverse connection protection circuit, which can prevent the module from burning when the power is connected in reverse. A LED display is available for monitoring the ambient temperature and humidity at the same time. Three kinds of probes can be selected to fit to various applications.
Applications
- Electronics, medicine
- Air conditioning purification
- Food hygiene
- Hospitals
- Large stations.
Features
- Reverse connection protection circuit;
- High temperature 120℃;
- Real time display of temperature and humidity;
- Dust prevention
- Rain resistant
- RS485 communicaton
