How to monitor the content of PM10 and PM2.5 in the air. It is one of the important contents of air governance work. The air quality monitoring stations is an air quality sensor. Built-in high-quality laser probe. but Generally speaking, The lowest detectable particle size is greater than 0.3 microns. The minimum measurable concentration can […]

background: SoilSoil is the most important growth substrate for crops. The root system of the crop needs to be taken from the soil. Absorb nutrients and moisture. To be able to grow normally. The soil quality directly affects crop yields. therefore. For agricultural practitioners. Only obtain accurate and sufficient soil quality data. In order to

Overview: Comprehensive soil sensor (five-in-one soil sensor). A sensor developed by Jingxunchangtong can monitor soil temperature, soil moisture, soil electrical conductivity (EC), soil ph, soil nitrogen, phosphorus and potassium index in real time. The soil sensor adopts imported chip inside, which has low power consumption, high sensitivity and stable signal. The probe part adopts special

Background: With the integration and development of network mobile technology and the democratization of innovation. The construction of smart cities is getting faster and better. We are walking on the road in the city, and we will see a smart public toilet at a distance. Smart public toilets are beautiful, comfortable, hygienic, tidy and intelligent.

Preface Carbon dioxide can generally be produced by high-temperature calcined limestone or the reaction of limestone with dilute hydrochloric acid. Mainly used for refrigerating perishable food (solid), refrigerant (liquid), manufacturing carbonized soft drink (gaseous state) and solvent for homogeneous reaction (supercritical state), etc. Regarding its toxicity, research shows. Low-concentration carbon dioxide is non-toxic, while high-concentration

water conductivity sensor overview Water conductivity (EC) can often represent the cleanliness of a pool of water. It can be used to judge the water quality of basic aquaculture. More professional data can be obtained by measuring the conductivity. The conductivity will fluctuate according to temperature changes. sensor for water quality monitoring The water quality

Overview of the grid air environment monitoring system: Jingxun’s grid-based monitoring network air pollution monitoring system. And use the Internet of Things technology to obtain the data of each monitoring point in real time. Based on GIS technology, the air quality map is presented. At the same time, the monitoring data can be analyzed and

Summary: Jingxun’s grid air quality monitoring system can sequence the multiple test signals of each monitoring sensor and analyzer. Enter the independent (DTU) transmission channel of the wireless communication node device DVR through the interface protocol. After lightning protection, it is input to the data collector in the unit. The collector transmits the collected data

Why buy a handheld barometer? If you are an amateur or professional. Its daily activities are highly dependent on the weather. Then you need a handheld barometer . This way you can carry out daily activities in a prepared manner. Portable weather station equipment will help you monitor various weather conditions. And to provide you

Background For crops and plants, the temperature, moisture, salinity and other parameters in agricultural and forestry soils have a great impact on the growth of crops. In order to better serve the production of agriculture and forestry, the Internet of Things based on the Internet is constantly developing. Various advanced IoT equipment instrument have begun
