Sensirion SEK-SHT40A-AD1B Temperature Evaluation Kit is used to evaluate the SHT40A Relative Humidity/Temperature Sensors. The SHT40A sensors are 16-bit, high-accuracy, automotive-grade digital sensors for measuring relative humidity and temperature with different accuracy gradings. The kit includes three SHT40A sensors on an FPCB and a 1-meter-long RJ45 adapter cable. SEK-SHT40A-AD1B operates in a -40°C to +125°C temperature range and a 2.3V to 5.5V supply voltage range.
