OEM Humidity / Temperature Module alterations according to customer specifications possible The EE03 is an inexpensive, highly accurate, temperature and humidity measurement module for OEM applications that communicates via a two-wire digital protocol. Originally designed and manufactured for the automotive industry, this device has excellent long-term stability and is ideal for a wide range of applications that require remote or embedded RH and temperature measurements. The EE03 plug-in module design also allows for ambient air monitoring or measurement of surface humidity andtemperature to detect nearcondensation (dew point)conditions. For applications in salt air or harsh environments, the EE03 is also available with an optional protective coating. The EE03 features an embedded microprocessor that retains calibration data, and provides a full-range, temperature corrected humidity output. The simple E2 digital protocol used by the EE03 allows for lowcost integration with other devices utilizing microprocessor based control or monitoring. Typical Applications HVAC & economizer control automotive appliances consumer products humidifiers dehumidifiers medical technology digital two wire output for RH and T qualified for surface condensation monitoring interchangeable plug-in design integrated easily to systems compact design low power consumption cable length up to 10m (32.8ft) optional protective coating for harsh environments traceable calibration Technical Data Measuring values Relative Humidity Sensor HC103 Digital output (2 wires) output value: 0.00...100.00% RH Working range 0...95% RH with coating 0...100% RH Accuracy at 21°C (70°F) ±3% RH (10...100% RH) Traceable to intern. standards, administrated by NIST, PTB, BEV...
