- IoT Sensor buildup based on Nordic nRF52840. It has temperature sensor (a lot more in future i.e. humidity, pressure, accelerometer etc.). - Periodically measures temperature at user defined time interval and transmit to it's receiver (we have designed a special receiver based on ESP32). - We have used encrypted data format to transmit data to it's receiver.
