Sensirion SHT7x Datasheet and User Guide
The SHT7x family (including SHT71 and SHT75) are fully calibrated relative humidity and temperature sensors with a digital output. They combine a capacitive humidity element and a band‑gap temperature element in a compact pin‑type package, offering low power consumption, high stability, and a 14‑bit temperature/12‑bit humidity resolution.
The guide details operating conditions, recommended soldering practices, storage handling, wiring considerations, and the 2‑wire serial interface (SCK, DATA) with pull‑up resistors. Electrical characteristics, command sets, measurement procedures, and conversion formulas are provided, along with reconditioning steps for sensors exposed to extreme conditions.

Questions answered in these manuals
What supply voltage range does the SHT7x sensor require?
The sensor operates with a supply voltage between 2.4 V and 5.5 V, with 3 V typical for best accuracy.
How can a sensor be reconditioned after exposure to extreme conditions?
Bake the sensor at 100 – 106 °C at <5 %RH for 10 h, then re‑hydrate at 20 – 30 °C and ~75 %RH for 12 h.
How many bits of resolution are provided for temperature and humidity?
Temperature is measured with 14‑bit resolution and humidity with 12‑bit resolution.
