Hello
We are currently looking for a NO2/NOx sensor for a research project. This will be attached to a multicopter drone and will measure the NO2/NOx concentration in a vertical profile in the lower atmosphere. The sensor needs to meet the following requirements:
Mass: max. 1.5kg
Max. dimensions: 300x80x80 mm
Power supply: <= 24V
Protocol: I2C, serial or CAN (has to work with Raspberry Pi or Arduino)
Humidity range: 10-90% r.H.
Heated: Yes (to allow measurements at higher humidities)
Measuring range: 0-1 ppm (or higher, as long as the measuring accuracy does not suffer)
Linearity: 4% of reading < 5 ppb
Response time: < 180s
Zero drift and span drift: < 6 ppb in 12h
Does BOSCH sensors offer a sensor that meets these reuqirements?
