A rainfall recorder (or rain gauge, rain gauge) is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in an area over a period of time (the measurement of snowfall requires the use of a snow gauge). common types of rain sensor According to the different measurement principle of the rain […]
Soil NPK sensor refers to the soil nitrogen, phosphorus and potassium sensor, also known as the soil nutrient speed tester, is suitable for detecting the content of nitrogen, phosphorus and potassium in the soil. how the soil NPK sensor works ? ①: Combined assayThe existing combined determination methods can be divided into two categories, one
Soil moisture sensor is also known as: soil moisture meter, soil hygrometers. It is mainly used to measure the relative water content of soil, to monitor soil moisture, and to protect agricultural irrigation and fore Soil moisture working principle Soil sensors are mainly used to measure soil volumetric water content for soil moisture monitoring and
The wind speed sensor is a device used to measure the wind speed. What is a wind speed sensor ? The wind speed sensor is a device used to measure the wind speed. It is small and light, easy to carry and assemble. According to the working principle, it can be roughly divided into mechanical

A temperature and humidity sensor is a sensor device equipped with humidity sensitive and thermal elements that can be used to measure temperature and humidity, some with on-site display, and some without on-site display. Temperature and humidity sensors are widely used in various fields of production and life due to their small size and stable
The temperature and humidity sensor mostly uses the temperature and humidity integrated probe as the temperature measuring element, collects the temperature and humidity signals, and processes them through the circuits such as voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection. After that, it is converted into a current signal
The temperature switch belongs to a temperature control instrument. When the temperature in the line is too high, the temperature switch will be triggered to disconnect the circuit, so as to avoid equipment burnout or even electrical accidents; when the temperature drops to within the normal range, the circuit is closed , return to normal

Wireless temperature sensor also called wireless temperature transmitter. Wireless temperature sensor acts as a battery-powered temperature measurement monitoring system with the function of measuring the gauge temperature of gases and liquids in a piping. wireless temperature sensor working principle The sensing element of the wireless temperature transmitter is PT100 platinum thermistor, and Lora/4G wireless module is used
The temperature transmitter adopts thermocouple and thermal resistance as the temperature measuring element. The output signal from the temperature measuring element is sent to the transmitter module. After voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse After protection and other processing, it is converted into 4～20mA, 0-5V/0-10V signal, RS485 digital
