    The battery-powered mobile device is built on the ESP32 architecture. The device wakes up every hour (deep sleep), receives data from the sensors, sends it via the GSM channel via the SIM800 module via the MQTT protocol to the server and goes back to sleep. There is a sample code. All sensors are connected via the i2c or 1-wire bus: ADC1115 (2 pcs.), BME280 (2 pcs.), DS18B20. Basic requirements...
