Outdoor CO2 transmitter
ID：eSenseOutdoor
The eSENSE Outdoor PCB is housed in an IP65 housing with breathers to support the flow of outdoor air. The eSENSE Outdoor includes an in-line thermostat in order that heating of the housing only takes place when the outdoor temperature warrants the use of the energy to maintain an above freezing temperature in the housing. Maintaining an above freezing temperature prevents the accumulation of ice crystals inside the Optical Bench Assembly, which could cause inaccurate CO2 measurements.
