Carbon Dioxide CO2 Measurements | Vaisala

CO 2 is a colorless and odorless gas that is soluble in water. It is the bubbles in the fizzy drink, a greenhouse gas, a byproduct of burning reactions, and in the air we exhale. CO 2 is itself noncombustible and inert gas, which makes reliable measurement challenging. The most dependable method for CO 2 measurements is Vaisala CARBOCAP ® carbon dioxide sensor, an optical infrared ...

Understanding Active Passive Infrared Sensors (PIR) and ...

· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies authorities, or maybe turns on a floodlight. IR radiation ...

IR (Infrared) Obstacle Detection Sensor Circuit

· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined.
