Crank position sensor is usually installed in the distributor, the control system is the most important one of the sensors. Its role is: detecting the engine speed, so-called rotation speed sensor; detects the piston top dead center position, it is also known as the only point sensor, including the detection of each cylinder for controlling the ignition TDC signal for controlling sequential spray oil first cylinder TDC signal

Soil temperature and humidity sensors for agricultural production
I do not know there is no kind of greenhouses around, greenhouses which are wall-mounted temperature sensor, use it to protect maintain the temperature and humidity in greenhouses, is to allow the plants to grow better, but the temperature is not enough light use , she also need suitable soil temperature and humidity, how to make sure that the soil temperature and humidity it, here's a look at to measure soil temperature and humidity are generally use a plug-in temperature and humidity sensors, of course, this plug-in temperature and humidity sensors and we usually refer to industrial plug-in temperature and humidity sensors are different. Average soil temperature and humidity sensor inserted relatively small, and the industrial use of different temperature and humidity sensors, soil temperature and humidity Crankshaft Position Sensor generally has several probes, and the probe length is not the same, so in order to better measure the soil at different depths temperature and humidity. Soil temperature and humidity Position Sensor are generally good corrosion resistance, because of the need often inserted into the soil, so the soil temperature and humidity sensor probes typically use 316 L special steel. With the country now have the importance of agriculture, soil temperature and humidity will further be adopted to serve agriculture, of course, now the soil temperature and humidity sensor price is very expensive, generally require thousands or even tens of thousands of prices, so that only relatively large farms will be used, along with the further development of sensor technology has been made of new materials, soil temperature and humidity sensor prices fell just around the corner, which will inevitably promote the temperature and humidity sensors to small self-employed. Soil temperature and moisture will use its good performance to serve agricultural production.
