Winsen's First Day at Sensor+Test 2023 (05/09-11, May)

SENSOR+TEST – the leading international trade fair for sensor, measuring and testing technology – opens its doors again in Nuremberg on Tuesday, 9 May 2023. Until 11 May 2023, around 350 exhibitors will inform visitors and experts from all over the world on site about the trends in the industry.

Winsen received many visitors coming from the world at our booth on the first day! A lot of new customers showed great interest on our sensors samples and planned afterward visit to Winsen headquarter in near future. Increasing visitors are to expect in the coming two days. Keep your focus on our news page!

Winsen Booth No.: 1-526

(Sensor+Test, 09-11,May2023)

Let's take a look at what sensors Winsen brought at this exhibition.


Security sensors refer to sensors used for security and monitoring, and are widely used in households, industries, businesses, and public places. Security sensors can sense changes in the surrounding environment, such as temperature, humidity, light, sound, smoke, gas, etc., and realize monitoring and control of the environment by connecting with the security system. Winsen safety protection sensors are classified according to the detected gas: carbon monoxide (CO), combustible gas (methane, propane, LPG, etc.), in addition, passive infrared motion detection (PIR motion sensor) is also an important component of safety protection sensors.

  • ME2-CO-Ф14x50-C Carbon Monoxide Sensor
  • GM-702B MEMS Carbon Monoxide Gas Sensor
  • MQ-2 Semiconductor Sensor for Flammable Gas
  • MC226A Catalytic Flammable Gas Sensor
  • RD-626W Pyroelectric Infrared Sensor
  • ZRD-09 PIR Motion Sensor Module


Winsen industrial sensor solutions are suitable for portable and fixed detectors and IoT systems in mines, metallurgy, power plants, chemicals, tunnels and other places. It can realize real-time monitoring and intelligent judgment and alarm for the leakage of dangerous gases (toxic and harmful gases, flammable and explosive gases) and exhaust emissions in the factory area and operating environment, which can effectively prevent the occurrence of safety accidents, ensure the safe production of enterprises and the safety of the staff.

Winsen industrial safety sensors include carbon dioxide (CO2), toxic gas, oxygen (O2),combustible gas, and PID sensors

  • 4-in-1 Industrial Gas Detection Module ZCE04B
  • MH-711A Infrared CO2 Gas Sensor
