Test Our Humidity Sensors with Sensirion's Evaluation Kit
Our evaluation kits enable easy testing of our humidity sensors. We offer four different types of evaluation kits:
- The Evaluation Kit EK-H4 for SHT21, SHT31, and SHT71 on PCB:
Easy-to-use plug-and-play system; read out data of four SHTxx humidity sensors simultaneously; connect with a PC via USB - The Evaluation Kit EK-H4 for SHTC1, SHTW2, and SHT3x on Flex:
Same functionality as EK-H4, but sensor samples are provided on flex PCB for easy integration of sensors into limited spaces - The Evaluation Kit EK-H5 for SHT21 on PCB and SHT31 on PCB and Flex:
Very simple system (USB stick, sensor cable and connector) enables fast and easy testing; read out and display sensor data on PC with minimum effort - The Evaluation Kit EK-H5 for SHTC1, SHTW2, and STSC1:
Same functionality as EK-H5, but designed for evaluation of 1.8 V sensors
Environmental conditions have a major impact on our well-being, comfort, and productivity. Sensirion’s sensor solutions provide detailed and reliable data on key environmental parameters such as humidity, temperature, volatile organic compounds (VOCs), particulate matter (PM2.5), and CO2. Environmental Sensing opens up new possibilities to create smarter devices that improve our comfort and well-being as well as increase energy efficiency in a wide variety of applications.
We accompany you through the entire product development process, from the initial idea to product launch and beyond. Our expertise ranges from prototype construction, design-in support and use-case development to inline testing at the mass production stage.
