power Distance sensing with comparator Electrical ...

The comparator circuit will comprise of an opamp powered with only a +5V voltage supply. There will be a InfraRed sensor to sense the distance. The idea is to turn on a vibration motor only when the user is 2 cm or closer to an object. The output voltage of the IR sensor is proportional to the distance of the object it is sensing.

Key Factors for Poultry House Ventilation | The Poultry Site

The concentration of carbon dioxide, ammonia and other harmful gases will increase to unacceptable levels. Table 1 indicates the level of some of the gases that research has shown to be critical and the level that is desirable. As the ventilation system exchanges the air in the building, it brings in the oxygen needed to sustain life and ...


Carbon Dioxide (CO HVAC Basics Honeywell

Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air quality equation. Low CO2 levels do not indicate good air quality while high CO2 levels do not mean that air is harmful. So CO2 sensors should be presented and sold as sensors of CO2 levels that provide information ...


CO2 sensor: Groene, oranje en rode LED knipperen – Zehnder NL

Onze CO2 regelingen zijn voorzien van gevoelige sensoren. Wanneer de groene, oranje en rode LEDS op de CO2sensor knipperen dan kan dat betekenen dat er geen stabiele CO2 meting kan plaats vinden, of dat de luchtkwaliteit gedurende een langere tijd niet op het gewenste niveau kan worden gebracht.
