Heat Stress Detector With Timer - TWL-1SR

Smart Heat Stress Detector that measures Wet Bulb Globe Temperature (WBGT), Thermal Work Limit (TWL), Globe Temperature and Dry Bulb Temperature. The TWL-1SR also has a timer that counts according to TWL value. When it expired, the device will notify the pager carriers remotely. It reminds you to take actions. 433 MHz technology is used to offer better penetration ability and 200 meter coverage in an open area is achieved.
