MPR121 is used in different industrial projects and electronic devices such as mobile phone and remote control systems. In today's post, we will have a look at its working, pinout, protocol, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have ...
Hello peeps! I hope you are having a good day. We all know carbon monoxide is a dangerous and harmful gas that can even be fatal. It is a colorless and odorless gas so it is difficult to sense its presence therefore, different types of sensors and indicators are required to make the places safe especially those where there is a chance for carbon monoxide gas production as a byproduct. Here, one of the most promising detectors is the MQ-7 carbon monoxide sensor which instantly detects and indicates the presence so the users may save their lives. This is the most popular choice for this purpose because of its low cost, high performance, and instant response.
This article will commence by introducing the MQ-7 carbon monoxide sensor. Subsequently, we will delve into essential details from it ...
Hi readers! I hope you are doing well and learning new things daily. Today, we have a detailed overview of the MAP(Manifold Absolute Pressure) Sensor, its working principle, types, structure, and features. The Manifold Absolute Pressure (MAP) sensor is a crucial element in a vehicle's engine to control pressure. The MAP sensor measures the pressure inside the intake manifold and transmits this data to the ECU so that fuel injection, ignition timing, and air-fuel mixture can be optimized. The MAP sensor is used to ensure engine efficiency, performance, and fuel economy.
The MAP sensor functions by the transformation of manifold pressure variations into an electrical signal, which is then interpreted by the ECU to calculate engine load. It is complemented by other sensors, including the M ...
