Measures carbon dioxide levels in the air / room. Long life and reliable long-term stability. Suitable for detecting carbon dioxide in concentration range 0 to 10000ppm.
Specifications:
- IC: LM393 MG811 sensor
- Supply voltage: 6Vdc
- Analog and TTL output (TTL is low-efficient)
- Analog output: 0~2000mV, (higher CO2 concentration, lower voltage)
- Adjustable TTL output sensitivity
- Indikator LEDs:
- For TTL level signal output
- Supply voltage
- Dimensions (L x W x H): 32 x 22 x 27mm
Note: This is a "maker" module for developers. It is delivered without any further instructions than what you find here.
