Wireless Temperature Humidity Indicators
Published on : Tuesday 30-11--0001
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.
Basic Features:-
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.
