Electronic water level measurement gauge is a new type of water level measurement sensor, which is composed of a PCB circuit board, a common electrode, detection electrode, epoxy resin, metal shell, cable, etc. Working principle of electronic river water level gauge Renke Electronic Water Level Gauge RS-DR-*-1 uses a series of electrodes arranged at equal […]

Monitoring of toxic and harmful gases such as formaldehyde and carbon monoxide in the home environment After the renovation of many new houses, more than 90% of harmful gases seriously exceed the standard, and the indoor formaldehyde concentration may exceed 2.5ppm, and some may even exceed 10ppm. Therefore, formaldehyde sensors, air quality sensors, TVOC sensors,

Compared with the traditional electric plate type air negative ion detector, Renke negative oxygen ion detector designed with the principle of double concentric cylinders can effectively solve the inherent electrolytic edge effect of the parallel plate type negative ion detector. The double structure of the concentric cylinder itself The special air intake method can maintain

Cold chain transportation A cold chain transportation refers to a vehicle with an insulated compartment and a refrigeration device. Among them, the structure of medical refrigerated vehicles is basically the same as that of ordinary refrigerated vehicles such as food and dairy products. They are composed of the running part of the special vehicle chassis,

The rain and snow sensor is a qualitative measuring device for measuring whether it rains or snows outdoors or in nature. It is equipped with imported intelligent microprocessors and advanced detection circuits. The surface adopts grid electrodes and uses the conductive characteristics of water. When there is rain or snow When it falls on the

RS-NPK-SC-1 is a soil tester developed by Renke that can quickly detect soil temperature, moisture content, electrical conductivity, and nitrogen, phosphorus, and potassium factors, and display the values on the LCD screen. The Renke soil tester is equipped with a 4000Mah lithium battery as standard. It can be used for more than 3 years in

The portable soil moisture monitoring system consists of a portable multi-channel soil data collector and a soil sensor. It is a monitoring system integrating soil information collection, data display and storage. Soil analyzer composition 1. The portable multi-channel soil data collector adopts the latest digital integrated circuit technology and international detection technology to make an

The portable ozone meter is an instrument that can be carried with you to detect ozone. Handheld ozone detector Technical Parameters: Range: 0-10ppm, 0-5% Accuracy: ±3%F.S (better than similar portable ozone detector accuracy) Working temperature: -10～+55℃ (better than the working temperature range of a similar portable ozone detector) Working humidity: 15～95% relative humidity (non-condensing) LCD

How to wire 485 and analog sensors? RS485 remote temp and humidity sensor has two-wire and four-wire connections. The four-wire system can only achieve point-to-point communication, which is rarely used now. Nowadays, the two-wire connection method is mostly used. This wiring method is a bus topology. Up to 32 nodes can be connected on the

Application areas: agricultural greenhouses, smart breeding, industry outside air temperature humidity sensor It adopts a wall-mounted high-grade enclosure with a protection grade of IP65, rain and snow proof, and good air permeability. The circuit adopts an American imported industrial-grade microprocessor chip and imported high-precision temperature sensor to ensure the excellent reliability, high precision, and interchangeability
