Delay OFF Lamp Timer Circuit
This delay off lamp timer circuit will automatically switch OFF a connected lamp after a predetermined time has elapsed. This time delay can be adjusted with a variable resistor or a potentiometer. The circuit is initiated by pressing a push button, which causes the connected lamp to switch ON. The lamp will continue to remain […]
Arduino Barometric Pressure Sensor Circuit – Working and Interfacing Details
In this article we are going to explore, what is a Barometer and how to interface a barometric BMP180 sensor with Arduino. We will also be exploring some of its important specification and finally I have explained how to predict weather using barometric readings. What is Barometer? Barometer is an instrument for measuring atmospheric pressure. […]
Solar Panel Voltage Regulator Circuit
In this post I have explained how to construct a simple solar panel regulator controller circuit at home for charging small batteries such as 12V 7AH battery using small solar panel Using a Solar Panel We all know pretty well about solar panels and their functions. The basic functions of these amazing devices is to […]
Vibration Meter Circuit for Detecting Vibration Strength
In this article I have explained a couple of simple vibration meter circuits which can detect and measure the strength of mechanical vibrations. Video Clip demonstrating the Vibration meter working The proposed circuits are built using transistors and also with an IC for getting a bar graph LED sequence for the level indications. The bar […]
Simple Vibration Sensor Circuit
As its name suggests, this simple vibration sensor circuit using piezo transducer allows for the detection of vibrations to which its sensor is subjected. Unlike superficial pressure sensors whose resistance varies depending on the force they are subjected to, the transducer used here is only sensitive to variations in pressure exerted on its sensitive face.
