Wireless Temperature Humidity Indicators:-
The Wireless Temperature Humidity Indicators STH-200-Series along with the local receiver unit called as Wireless Control Unit WCU-100, are one of the recent technologically upgraded products which work through GSM/GPRS systems and can easily interface with Temperature and Humidity sensors. They eliminate the use of physical cables that were required for signal transfer between the conventional indicators & multi-channel monitors or data loggers. The wireless data communication features integrated within these devices, use the constantly evolving technologies related to the Internet of Things – IoT category. These devices can be easily operated using a Battery supply or through Solar Panel supply or 24VDC SMPS or 5V, 2A Adapter from AC mains.
Parameters highlighted by these devices are –
- Battery percentage
- Status of the device
- Fault condition
- GSM network status
- Sensor readings
- They are easy to use and work efficiently
