Abstract:

A mole trap prototype with a wireless signaling module in WiFi standard has been made. The ESP8266 chip built-in in the form of a module called ESP-12e was used to signal the wireless event related to catching the mole. Recording of the trap entry event was made using a contact sensor connected to the AZ850P2-3 latching relay. Network communication between the trap and the client has been developed. Original software for the ESP8266 chip that allows you to use the trap within the range of different WiFi networks has been made. The test system was powered by a lithium-polymer battery with a capacity of 1350 mAh and a voltage of 3.7V through a voltage regulator. The device's energy demand was measured by measuring the current flow during the highest energy consumption.  It was found that on one battery charge the trap could be active for up to a year depending on how often it would be used. All trap functions, depending on the WiFi network range, have been tested in field conditions. No mole suffered from these tests.
