IoT Based Biometric Door Lock using Fingerprint Sensor and NodeMCU ESP8266
0 Comments
Fingerprint scanner sensors are used at many places like Industries, Offices, Schools, Colleges and Hotels. By embedding IoT with the Fingerprint sensor, we can elevate the Fingerprint-based security system project to the next level. So in this project tutorial, we are going to build and IoT Based Biometric Security System using the GT5111C3 fingerprint...
IoT Based Air Pollution Monitoring using NodeMCU and MQ135 Gas Sensor
0 Comments
There are different types of gas sensors to detect different gases. Here in this project we are going to use MQ135 gas sensor to sense the pollution content in the surrounding area and then to monitor these values over the Webpage. The circuit consists of a simple connection and takes fewer components to have...
IoT Based Smart Dustbin using NodeMCU
1 comment
In this project tutorial, we are going to make an IoT based Dustbin. You can check whether the dustbin is full or empty through a webpage. This dustbin updates its status in percentage in every 5 seconds, and when the dustbin is filled more than 70%, it sends an email that your dustbin is...
