Monitoring of stationary and mobile objects. Determine the measured voltage/temperature, the status of electrical signals, and optionally the current GPS position of the object at any time via SMS. Conveniently switch one of two relay outputs at any time via SMS or phone call. Receive notifications via SMS and email when, for example, the power supply fails, the temperature falls above or below adjustable values, or optionally, when the monitored object moves outside adjustable GPS coordinates. With the AREA function, you can specify GPS corridors within which the object is allowed to be. If it exits this area, an immediate warning message is sent to all stored phone numbers (SMS). Receive the current GPS position of your monitored object at regular intervals. Applications: Monitoring and remote control of heating, air conditioning, and cooling systems, remote control of doors and garage doors, control and monitoring of motion or fire detectors, level sensors, monitoring the position of mobile objects, and much more.
