Prevetion of Harmful Gases in closed Environment:

Dec 2019 - May 2020

“System for Alerting, Monitoring and Controlling Heat Stroke inside closed environment” (Garethiya, 2015). Has proposed a simple and effective solution to alert owners about the possibility of heatstroke inside it if any person is present and thus apparently avoiding death due to suffocation. And also making system beneficial to the owner using sensor and electronic units. System includes Fire sensor and GSM module to send messages.

Prepaid Energy Meter Using Arduino and GSM Module:

Aug 2019 - Dec 2019

In this project we built an automated system by using Arduino and GSM module. We can recharge the electricity balance through this system, just by sending a SMS. It can also disconnect the home power supply connection, if there is low or zero balance in the system and this system will also send some updates to user’s mobile phone like low balance alert, cut off alert and recharge alert.

Fingerprint Based Biometric Attendance System using Arduino:

Jan 2019 - Apr 2019

In this fingerprint attendance system circuit, we used Fingerprint Sensor module to authenticate a true person or employee by taking their finger print as input in the system. Here we are using 4 push buttons to Enrol, Delete, UP/Down. ENROLL and DEL key has triple features.

Pull Pin Security Alarm System:

Aug 2018 - Nov 2018

The circuit consist a pin which is fixed to the pocket and the other end is attached to the circuit. The circuit remains inactive until the wallet is in your pocket as the circuit gets activated when the wallet is pulled from your pocket. Then Loud speaker attached to circuit makes sound.
