(approx. 88.28$ USD )

Product Description:

This atmospheric pressure sensor is easy to interface thanks to the simple RS-232 interface and protocol it uses. Also, for applications requiring a temperature, relative humidity and dew point reading, a Sensirion sensor such as the SHT15 can be wired to the unit.


  • Internal Atmospheric sensor specs:
    • Range: 15 to 115 kPa (2.2 to 16.7 psi).
    • Accuracy: 2% Maximum Error from 0° to 85°C.
    • Resolution: 10-bit (±0.1kPa)
    • Temperature compensated.
  • Connectors:
    • RS-232: DB9-F DCE
    • Power input: 2 position terminal block
    • External temperature/humidity sensor: 4 position terminal block
  • Supply voltage: 7-17v, 18mA typ. (power supply not included[1])
  • Cable and power supply: Not included [1].
  • External temp./RH sensor: Not included. Supports Sensirions sensors such as the SHT15.
  • Temperature range: -40°C to +70°C.
  • Protection from Harsh Environments: Protected using a layer of Silicone Conformal Coating providing superior protection against dust, humidity and corrosion.
  • Enclosure: ABS Plastic. NOT waterproof. Use adequate housing if necessary.


This product uses a simple ASCII communication protocol that can be very easily implemented using most programming languages. The protocol is fully documented in the manual.

[1]: Due to the broad range of applications this product find uses in, we prefer not to offer the RS-232 cable and power supply since the system integrator is in a much better position to make a good choice.
