Reed Switch is a special switch and a main component for reed relay and proximity switch. Reed switch is usually comprised of two soft magnetic material and metal reed contacts which will disconnect itself when there is no magnetic. In addition, some reed switches are also equipped with another reed acting as the third normally-closed contact.
This analog gas sensor - MQ2 is used in gas leakage detecting equipment in consumer electronics and industrial markets. This sensor is suitable for detecting LPG, I-butane, propane, methane, alcohol, Hydrogen and smoke. It has high sensitivity and quick response.
MQ-4 application: it can be used in household and industrial-level gas leakage detection device to detect natural gas and methane. It is featured with wide detection range, high sensitivity, fast response and recovery time, with excellent stability, long service life and simple drive circuit.
The sensitivity of MQ-5 gas sensor to propane, propane and methane is quite high, and the methane and propane can be well detected. This sensor can detect a variety of combustible gases, especially natural gas, making it a low-cost sensor for a variety of applications.
The sensitivity of MQ-6 gas sensor to propane, butane and liquefied petroleum gas is quite high, and the natural gas can also be well detected. This sensor can detect a variety of combustible gases , making it a low-cost sensor for a variety of applications.
The sensitivity of MQ-8 gas sensor to hydrogen is quite high, it can also detect a variety of other gases containing hydrogen. This sensor, which is suitable for a variety of applications, is definitely a good catch.
keyestudio water sensor is easy- to-use, portable and cost-effective, designed to identify and detect water level and water drop. This sensor can measure the volume of water drop and water quantity through an array of traces of exposed parallel wires.
The sensor is set with two probes inserted into the soil. With the current goes through the soil, the sensor will get resistance value by reading the current changes between two probes, and then convert such resistance value into moisture content. The higher moisture (less resistance), the higher conductivity the soil has.
