Material Storage Level Controller Circuit
In this post I have explained a simple material storage level controller circuit which can be used for automatically activating and deactivating a storage filling motor whenever the storage container is filled to its stipulated threshold level. The idea was requested by Mr Sladjan. Circuit Objectives and Requirements I need help with the engine control […]
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. […]
LPG Leakage SMS Alert using MQ-135 – Get Warning Message in your Cellphone
In this article I will show how to construct an GSM based LPG leakage SMS alert circuit using Arduino, which alerts the recipient via SMS and surrounding people via beep, when LPG gas leaks out from the LPG cylinder or if there’s leakage due to improperly closed valve. Using MQ-135 as the Sensor We are […]
MQ-135 Air Quality Sensor Circuit – Working and Interfacing with Program Code
In this article I have explained how to interface air quality sensor MQ-135 with Arduino. We will see overview of the sensor and construct a project which detects LPG gas leakage and see some relevant readings in serial monitor. What is MQ-135 sensor? MQ-135 is an air quality or air pollution measuring sensor device. It […]
How to Make a Transformer Winding Counter Circuit
In this post I have explained how to make a simple transformer winding counter circuit using ordinary LEDs and also through an advanced digital display circuit. The idea was requested by one of the dedicated readers of this blog Circuit Objectives and Requirements I want a circuit which counts a number of turns for winding […]
