Node MCU code for Detecting Temperature, along with the IR sensors, buzzers, LEDs and servo motor. All the sensors are attached to the NODEMCU ESP8266 Wifi Development Board. This setup is connected with the machine learning model which detects the mask via an IP webcam and then updates it to Firebase. The Node MCU is also connected to Firebase, which pulls the mask detection result from firebase and proceeds with the detection and updates it to Firebase again. These two setups are connected to eachother using Firebase's Realtime Database.
