The DSM501 dust sensor senses the density of particles in the air. It can be used to quantitative particle (> 1 micron) measurement; which can sense tobacco smoke, pollen, and dust particles. The sensor consists of a light emitting diode, detector, signal amplifier circuit and heater, it can be used in applications such as the air cleaner or air purifier.
- $21.00 In Stock
An infrared emitting diode and a phototransistor are diagonally arranged into this device, which allows it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke and air purifier systems. The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with...
