Hello readers! I hope you are doing great. Today we are discussing the features and details of the MQ-4 methane gas sensor, which belongs to the popular gas sensor MQ family. We have been working on other gas sensors as well, but MQ-4 is particularly suitable for detecting the presence of methane gas. This sensor is more popular because methane gas and compressed natural gas (CNG) are widely used for cooking and other related purposes. MQ-4 methane gas sensor is an important part of the home safety system. Some other advantages of this sensor are, that it responds instantly and has a potentiometer that adds versatility to its functions.
In this article, we are going to study the MQ-4 methane sensor from scratch. We’ll go through its introduction and will study the basic components of it ...

Hi readers! Hopefully, you are well and exploring technology daily. Today, the topic of our discourse is the VL6180 Time-of-Flight (ToF) Proximity Sensor. You might already know about it or something new and different.
It is a Time-of-Flight (ToF) proximity sensor, VL6180 from STMicroelectronics. It was built specifically to accurately measure the distance of IR light. This device is actually working based on infrared emission towards an object, the reflection of that emission will travel back to the sensor for it to compute distance; and due to the time-of-flight principle applied to this kind of computation, accuracy to measurement could be well given.
One of the key features of the VL6180 is its compact form factor, which makes it ideal for integration into space-constrained applicat ...
Hey students! Welcome to another episode of the MQ gas sensor series. Today, we are interested to learn about the high-performance sensor that is used to detect the presence of benzene gas. This is the MQ138 gas sensor and it instantly detects the target gas because it has tin dioxide as the sensing element. Usually, it can detect multiple gases and is considered as the Volatile organic compounds (VOC) sensor but the most significant target gas of this sensor is benzene therefore, we’ll pay attention towards the discussion of the benzene detection through this sensor. Many features of this sensor resemble other members of the MQ gas sensor series and we’ll read its basic features and specifications in detail.
In this article, we’ll initiate the discussion with the basic introduction of t ...
Hi readers! I hope you are doing well and exploring new things daily. Do you know about the crankshaft position sensor? Today we will discuss the crankshaft position sensor with a detailed overview of its working, functioning, structure, and types. The crankshaft position sensor is an important part of internal combustion engines in modern automobiles. It finds the crankshaft’s position and rotational speed (RPM) and transmits this information to the Engine Control Unit (ECU). For optimum performance and fuel efficiency in making a vehicle operate smoothly, the crankshaft position checks the ignition timing, fuel injection, and valve timing. In the case of a non-functional CKP sensor, the engine may behave in a manner that does not start at all, misfires or works inefficiently.
CKP senso ...
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 ...
