Ultrasonic sensor module HC-SR-04 This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. It is used to measure the distance of the obstacle …
IR Transmitter/Receiver IR transmitter and Receiver are commonly used in devices which can be controlled with the help of remote. TV remotes are the best example for IR transmitters. IR Led emits infrared rays which cannot be seen with normal open eyes as its wavelength is very low (700nm – 1mm) as compared to visible …
MQ Series Sensors MQ Series are a set of gas sensors that are used to identify different types of gases. They are very useful in measuring the gas concentration and can be used in sensitive areas such as chemical industries. Each type of MQ sensor is designed to detect specific gases. We’ve a lot of …
Triple axis magnetometer A magnetometer is used to find directions, by aligning itself with the earth’s magnetic field. There are many types of magnetometers such as fluxgate, magnetoresistive, magneto-inductive and others. Earth’s magnetic field is present in space which points towards the magnetic north. Current carrying conductor also generates a magnetic field around itself. Hence, …
IR Sensors, obstacle avoider sensor module IR Sensors, obstacle avoider sensor module The IR sensor is used to sense if there is some sort of obstacle in its line of sight. It does that by sending an IR (infrared) light from the transmitter end, which isn’t visible to the normal eyes, and then, if there’s …
Capacitive Touch Switch Module A capacitive touch switch module (TTP223) is a touch pad detector integrated circuit which works as a single tactile button, which means, it can be used to sense touch inputs as switch buttons and do the work accordingly. This touch detection IC is designed for replacing traditional direct button keys with …
Capacitive Touch Module Its amazing that we just touch our mobile screens and they work like magic and do things. Now it is very common so we might not feel very awed about it. But, if you think, that’s a great invention and leap of technology, where a simple touch can be used as an …
Button Switch Set A switch is an electronic component which is used to break connections between a circuit. It can be used to have two states, on or off. That is why it is also considered as a binary device. When an electronic switch is on, it is considered closed in a circuit. When the …
Timer IC – LM 555 A LM-555 Timer is a commonly used IC designed to produce a variety of output waveforms with the addition of an external RC network. The name 555 is derived from the fact that it has 3 resistors with values of 5Ω each. It is a highly stable device for generating …
Vibrating Motor Vibrating motors are small DC motors that are often used to send signals in form of vibrations, unlike sound. These motors are used in a lot of appliances and devices like cell phones, handsets, etc. It has two terminal wires that when connected through a battery produce the vibrations. A vibrating motor has …
