SHT4x
High-accuracy temperature and humidity sensor
SHT4x
High-accuracy, low-power I2C humidity and temperature sensor.
The SHT4x is the successor to the popular SHT3x: better accuracy, lower power and an integrated heater for condensing environments. It speaks standard I2C and is plug-and-play with Arduino

It's the pick when humidity really matters (HVAC, greenhouses, indoor comfort). Versus the BME280BHardwareBME280Temperature, humidity and barometric pressure sensorView profile, it drops pressure sensing but gains humidity accuracy and stability.
Pros
- High humidity and temperature accuracy
- Ultra-low power
- Integrated anti-condensation heater
Cons
- No pressure sensing (unlike the BME280)
- Pricier than basic sensors
