This project demonstrates a simple temperature and pressure monitoring system for a cold storage room using an Arduino, a TMP36 temperature sensor, and an Adafruit 16x2 LCD screen.

Arduino Uno TMP36 Sensor Working Principle: The TMP36 temperature sensor gives analog output proportional to the temperature. The Arduino reads this analog voltage from the sensor using the analogRead ...

A photocell and TMP36 temperature sensor are connected to the Arduino, then with a bit of code and USB host magic, the Android app shows the temp and amount ambient light present in the room.
