SHT1x is a humidity and temperature sensor with features including full calibration, digital output, low power consumption, excellent long-term stability, and SMD package.
The SHT1x family (SHT10, SHT11, SHT15) are surface‑mountable relative humidity and temperature sensors that provide a fully calibrated digital output. Each device integrates a capacitive humidity element, a band‑gap temperature element, an ADC, and on‑chip memory for calibration coefficients. The sensors are supplied in an LCC package and are RoHS/WEEE compliant.
The document includes detailed performance data, electrical characteristics, mechanical dimensions, recommended soldering and handling procedures, and interface specifications for the 2‑wire serial bus. Evaluation kits EK‑H2 and EK‑H3 are described for prototype testing and multi‑sensor applications.
| Humidity accuracy (typical) | ±2 %RH |
|---|---|
| Temperature accuracy (typical) | ±0.5 °C |
| Supply voltage range | 2.4 V – 5.5 V |
| Recommended supply voltage | 3.3 V |
The recommended supply voltage is 3.3 V.
The EK‑H3 kit allows parallel application of up to 20 sensors.
The sensor should not be active for more than 10 % of the time, i.e., at most one measurement per second at 12‑bit accuracy.
