Latest Upgraded Technologies.
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.

Basically, these devices can be used for all those similar applications where the conventional cabled Temperature / Humidity Indicators were being used. But, extensively, these devices are required in areas where use of cables is inconvenient due to proximity i.e. the indicators and multi-channeled monitoring control units are placed far apart or on different floors or where the indicators or detectors are placed in confined areas. Hence, these devices find theirs usage in most of the applications of the following industries.
- Research & Development Laboratories;
- Pharma Warehouses;
- Cold Rooms & Cold Storage in Pharma or Food Industry.
- Clean Room Monitoring;
- Cold Chain Monitoring;
- Pulp & Paper Industry.
