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. […]

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. […]
GSR Sensor Circuit for Biofeedback Measurements
In this post I have explained how to build a very simple GSR sensor circuit using just a couple of transistors and a few other passive components. A GSR (Galvanic Skin Resistance) sensor, also known as a skin conductance or electrodermal activity sensor, measures the electrical conductance of the skin, which changes in response to […]
Shock Vibration Detector Circuit using 801S Sensor
The shock alarm module that we are presenting to you can be used in a house as well as in a car. Given its low manufacturing cost, it can be replicated in several copies and connected to different positions at home. It can be also installed in a vehicle where it will trigger a siren […]
Vibration Sensor 801S Datasheet Explained
The 801S vibration sensor is a typical vibration detection and measurement module. The following are some of its main technical features, datasheet and characteristics: Datasheet in Details The 801S vibration sensor is very sensitive and can pick up even the smallest vibrations in its surroundings. Frequency Range: The module is made to detect vibrations that […]
ON/OFF Relay Switch Circuit using Reflection Sensor
This 220 V ON/OFF electronic relay switch can be toggled ON/OFF simply by alternately bringing your finger close to the reflection sensor CNY70. About CNY70 CNY70 is an infrared reflecting sensor comprised of an infrared emitting diode and a phototransistor housed in a tiny plastic container. The sensor operates by generating infrared light and sensing […]
