The S-NH3-01 is an industrial-grade IP65-rated electrochemical detection of solid polymers with a revolutionary innovative technique in electrochemical detection areas with wide applications in farming, industrial areas, and meteorological monitoring.

    Ammonia gases are the most common cause of the stinky smell in our daily life and it has a tremendous effect on our health. A small number of ammonia gases only make you suffer from a bad smell. However, when one area concentrates a large number of large ammonia gases, it will become toxic gas and hurt your olfactory system.

    There are different sources of ammonia gases whether by humans or by nature. One major source is the excretion produced by the livestock farming industry. Another major source is energy generation in heavy industry because burning coal, fuel, and natural gases produce a huge amount of ammonia gas, which increases the risk of improperly disposing of ammonia gas.

    RS485 NH3 Sensor S-NH3-01 adopts an imported sensor chip from Germany with the ability to monitor ammonia concentration, air temperature, and humidity at the same time. The sensor transmits data with the help of the RS485 Modbus RTU protocol. The sensor contains excellent features as it can respond to gas or environment with high speed and sensibility, tolerate disturbance, and adopts a compensation algorithm and adjustable standards, all of that assure the accuracy of the sensor. This equipment was powered by 5V DC, able to support most of the sensors in the market. Equipment can be easily integrated into most of the system without a complex setup procedure.

    Solid polymer electrochemical technology is a revolutionary innovation in the field of electrochemical detection. This technology is based on the principle of electrochemical catalytic reaction triggered by different target gas leading to sending out a different electrical signal that is directly proportional to the gas concentration. The sensor module is composed of three catalytic electrodes, a solid electrolyte, and gas diffusion holes. The gas reaches the working electrode of the sensor through the diffusion holes, an electrochemical redox reaction occurs on the porous micro-surface of the electrode, and the solid electrolyte conducts electron transfer and generates a current signal as an output. The current signal can characterize the gas concentration.

    Connect with Sensor Hub for Remote Transmission

    Sensor Hub Data Logger is an easy-to-deploy 4G cellular station. It uses the MODBUS-RTU RS485 protocol to communicate with sensors and can collect various sensor data simultaneously.

    Sensor Hub consists of 4 RS485 data channels. With extension hubs / RS485 splitters, it can connect with a maximum of 32 sensors simultaneously. The data is collected and sent to the cloud (either to the SenseCAP server or the client's private server) via 4G/3G/2G (as shown below).

    Designed with industry standards and IP66-rated enclosure, Sensor Hub is suitable for outdoor and harsh environments, resistant to UV, rain, dust, etc. GNSS is embedded for location tracking.

    Sensor Hub is also equipped with 10MB onboard memory, to store more than 700,000 measurements locally in case of a bad connection.
