Hebei Osu Electronics Hebei Osu OSA-BF11 odor sensor gas instrument

OSA-BF11 odor sensor is a product independently developed by our company. It adopts imported data acquisition chips and advanced production technology and surface mount technology,and the measurement data is accurate and reliable. It has been carefully calibrated during production,and the calibration data is stored in the internal memory. Measurement accuracy,linearity,repeatability,interconvertibility,consistency,etc.Very good. 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.

OSA-BF11 odor sensor supports multiple output methods. Wired output includes RS485 signals and voltage and current signals; wireless output includes LoRa,Bluetooth,WIFI,GPRS,4G,NB-IoT. In addition to LoRa and Bluetooth,the other four wireless outputs are All forms can be connected to the Osu Smart Cloud Platform to realize the monitoring and management of intelligent terminal data; RJ45 network output has three protocols (1. Cloud platform protocol,directly uploaded to the server; 2. Standard Modbus-RTU protocol; 3. Standard Modbus-TCP protocol). In addition,the sensor has built-in 1 to 2 relay switching outputs,and a buzzer prompts an alarm. The high limit or low limit alarm value of any parameter can be freely set through RS485.

（1) Multiple parameters can be detected at the same time,and users can customize parameter types according to needs.

（2) Rich human-machine interface,based onnewestThe color screen interface designed with the embedded idea can display real-time data of single or multiple parameters.

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

（4) Truly achieve low cost,low price and high performance.

（5) The building-type housing is compact in design and easy to install.

（6) The screen background color can be customized.

（7) Font color can be changed.

（8) Built-in 1~2 channels of relay switching output,buzzer prompts alarm.

（9) Digital linearization correction,high precision and high 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.
