Temperature and Humidity Sensor


s h t 15 d v



The SHT15 is a temperature/humidity sensor utilizing the Sensirion SHT15 integrated chip. A microcontroller, such as the BASIC Stamp® or the OWL 2pro, reads out the values via its two-wire digital serial interface, and then applies a little math to achieve ±2% humidity accuracy and ±0.5% Celsius temperature accuracy.

The chip and its accompanying electronics are mounted on a PCB board that can be fastened by the end user in various configurations. It is connected to a three-meter, four-conductor cable that terminates in bare wire leads (other terminations are possible–please contact us for your specific needs). The sensing element is protected from dust and other contaminants by a plastic cap that incorporates a GORE-TEX® vent. This, along with the accompanying electronics, are potted in epoxy.

The SHT15DV (photo, below) includes the Davis Instruments DV7714 radiation shield. In this configuration the SHT15 is mounted inside. The DV7714 can also be purchased unassembled.
