Hebei OSU Electronics Building Multi-parameter Sensor Gas Instrument

multi-parameter sensorIt is a product independently developed by our company.All adopt imported data acquisition chips and advanced production technology and surface mount technology,so the measurement data is accurate and reliable. It has been carefully calibrated during production,and the calibration data is stored in the internal memory. It is outst in terms of measurement accuracy,linearity,repeatability,interconvertibility,and consistency. In addition,the sensor has digital output and is fully interconvertible. It does not require complex verification and calibration. It is suitable for environmental equipment matching,instrument equipment integration,and a large number of general environmental tests.

Multi-parameter sensors can output a variety of signals,and wired output signals includeRS485signals and voltage and current signals; wireless output includesLoRa,Bluetooth,WIFI、GPRS、4G、NB-lOT,wireless output exceptLoRa,Bluetooth,the other four forms can be connected to the Osu Smart Cloud Platform to realize the monitoring and management of smart terminal data.；RJ45There are three protocols for network output (1,cloud platform protocol,upload directly to the server;2,standardModbus-RTUprotocol;3,standardModbus-TCPprotocol).In addition,the sensor has built-in1～2relay switch output,buzzer prompts alarm. accessibleRS485Freely set the high limit or low limit alarm value of any parameter.

The parameters that multi-parameter sensors can monitor include air temperature,air humidity,CO₂concentration,COconcentration,PM1.0/2.5/10.0,atmospheric pressure,formaldehyde,oxygen,ozone,volatile organic compounds,air quality,etc. (the measured parameters are customized according to needs),the monitoring parameters are complete,and the measurement data is accurate.

（1）Multiple parameters can be detected simultaneously,and users canaccording toAny customized parameter type required。

（2）Rich human-machine interface,color screen interface designed based on the latest embedded ideas,can display real-time data of single or multiple parameters。

（3）High integration,low power consumption and life。

（4）Really realize low cost,low price and high performance。

（5）Building-style housing is compact and easy to install.。

（6）Screen background color can be customized and font color can be changed。

（7）built-in1～2relay switch output,buzzer prompts alarm。

（8）Digital linearization correction,high precision and stability。

This product can be widely used in chemical fertilizers,biomedicine,food safety,environmental protection supervision,agricultural greenhouses,industrial production,livestock breeding,construction buildings,meteorological environmental protection,gardening flowers,home life and other fields that need to monitor environmental meteorology.

4.2Impedance Requirements for Current Signals

The multi-parameter sensor wiring instructions are as follows:

V: The voltage value collected by the collector,unit:V；

A: Current value collected by the collector,unit:mA；

RS485signal (default address01）：

standardModbus-RTUProtocol,baud rate:9600;Check bit: none;Data bit:8;Stop bit:1

7.1address

For example: the address to1The sensor address is changed to2,host→Slave machine

If the sensor receives correctly,the data will be returned along the original path.。

Note: If you forget the original address of the sensor,you can use the broadcast address0XFEInstead,use0XFEAt this time,the host can only connect one slave,and the return address is still the original address,which can be used as an address query method.

7.2Query data

Query the sensor (address is1)The data（21parameters),host→Slave machine

If the sensor receives correctly,the following data will be returned,and the slave→Host

（1）Please check whether the packaging is intact and whether the transmitter model and specifications match the product you purchased.。

（2）Do not connect while the power is on. Only after the wiring is completed and checked are correct can the power be turned on.。

（3）Users should not modify the soldered components and connected wires of this product when it leaves the factory.。

（4）The sensor is a precision device. Users should not disassemble it by themselves when using it,let alone touch the diaphragm to avoid damage to the product.。

（5）Avoid sticky particles from entering the sensor and prevent moisture from affecting the measurement performance.

The warranty period of this product is one year. Within twelve months from the date of shipment,our company will be responsible for free repair or replacement of any failure caused by sensor quality problems (non-human damage). After the warranty period,only the cost will be charged.
