This SMD humidity sensor is distinguished by a passive or active substrate on which the humidity cell is created in situ, without any connection wires, in opposition to a sensitive « chip » connected to a receiver by miniature electrical links.
This original design allows a high reliability and faithful features, because no uncertainties due to
connection elements will modify accuracy and response time.
Caracteristics:
- Low size 8x9x1mm
- Low cost version
- Ultra fast response time (0.1 s)
- Connected by conductive glue
- Utterly interchangeable without recalibration
- Defined accuracy from 1 % RH to 99 % RH
- Instant desaturation after long time condensation
- Suitable to automatic assemblings
- No package, allowing a very short response time and a
reduction of surface pollution problems - External electrode connected to electrical ground, banishing
any influence of leakage currents in comparison with electrical
0 (electrical and mechanical screening) - Operating range of temperatures from -90°C to +120°C
Applications :
- Meteo probes
- Moistening and dehumidification
- Airlocks control
- Greenhouse
