The sAIns-sense devices will taking measurements using sensors

In this project, I use a microcontroller based on the ESP32 chip which has an external antenna and battery sockets: LilyGO / TTGO T7 Mini32 V 1.3 (Hereafter it will be referred as TTGO-T7)

The photo below shows the details of TTGO-T7:
