E+E Electronik Introduces Digital Humidity Sensors With Integrated Contamination Protection
E+E Elektronik presents new digital humidity and temperature sensors, EEH110 and EEH210. An integrated coating reportedly protects the sensors from pollution for long-term stability under harsh conditions. Several interfaces and supply voltages (3 V or 5 V) allow for easy integration of the accurate RH/T sensors in a wide range of applications.
A special hygroscopic layer protects the active sensor surface from contamination and corrosion. Additional components, such as filter caps, are not required, according to the company.
Precise humidity and temperature factory adjustment ensures a high accuracy of ±2% RH and ±0.3 °C (±0.5 °F), according to the company. The measured values are available on I²C, PWM and PDM digital interfaces. EEH210 features a SPI interface, while EEH110 offers an analog output for relative humidity. Dimensions of 3.6 x 2.8 x 0.75 mm (0.14 x 0.11 x 0.03 inch) allow the sensors to be used in applications with space restrictions.
EEH110 and EE210 are optimized for mass manufacturing and can be processed automatically due to the DFN enclosure.
