Sensors enable us to receive signals from the outside world. Technically, sensors are objects capable of receiving a signal, and when this signal reaches the predefined level of sensitivity of the sensor, they are able to send information to the rest of the circuit. Sensors are often used in robotics, as they enable robots to communicate with their environment, be it by vision (light and colour sensor), hearing (sound sensor) or smell (gas sensor). We offer a wide variety of sensors for all applications and price ranges.

PMS5003 High Accuracy Particle Concentration Sensor

The sensors can be integrated into a variety of instruments associated with a concentration of airborne particles to improve equipment, provide timely concentration, and have Exact data.
Present the laser that scatters products on airborne particles, at the same time at a specific angle collect scattered light, changing the intensity curve that scatters over time.
The microprocessor uses the algorithm based on the MIE theory to deduce the grain size contained in the air and the concentration of the particles per unit and quantity. Characteristic: - Power supply: 4.5-5.5 VDC
- Measurement range: 0.3-1.0ï¼ ›1.0-2.5ï¼› 2.5-10 µm (micrometer)
- Accuracy of count: 50%@>
