      • Formaldehyde Sensor SFA30

        Formaldehyde Sensing Made Easy

        The SFA30 is Sensirion’s new digital formaldehyde sensor designed for easy integration into air purifiers, demand-controlled ventilation systems, or indoor air quality monitors. Based on Sensirion’s electrochemical technology, the SFA30 offers excellent formaldehyde sensing performance with a uniquely low cross-sensitivity to other VOCs. The sensor module’s on-board SHT sensor provides accurate humidity and temperature readings and enables a fully temperature/humidity compensated and factory calibrated formaldehyde concentration output in ppb.

    Digital Humidity Sensor SHTC3 (RH/T)

    The Standard for Humidity Sensing in Consumer Electronics

    The SHTC3 digital humidity sensor builds on the success of the proven SHTC1 sensor. Thanks to a broader supply voltage range (1.62 – 3.6 V) and higher accuracy (±2% RH, ±0.2°C) than its predecessor, it enables greater flexibility.

    Sensirion’s CMOSens® Technology offers a complete sensor system on a single chip, consisting of a capacitive humidity sensor, a bandgap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital communication interface supporting I2C fast mode. The small 2 x 2 x 0.75 mm3 DFN package enables applications in even the most limited space. The sensor covers a humidity measurement range of 0 to 100% RH and a temperature measurement range of -40°C to 125°C with a typical accuracy of ±2% RH and ±0.2°C. The broad supply voltage of 1.62 V to 3.6 V and an energy budget below 1 μJ per measurement make the SHTC3 perfectly suited to mobile or wireless applications powered by battery.

    With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors providing constant accuracy over a large measurement range, the SHTC3 offers the best performance-price ratio. Tape and reel packaging combined with suitability for standard SMD assembly processes make the SHTC3 ideal for high-volume applications.
