Reliable Sensor
Bought the SHT30 version. Much better accuracy than the old DHT11. Highly recommend for serious projects.

Great for Arduino projects
Works perfectly out of the box. Used it with an ESP32 and the I2C library. Readings are stable.

Works as expected
Simple to integrate. Just make sure you pull-up the data line if using single-wire mode.
5 FAQ
Q: Which library should I use?
A: We recommend the Adafruit SHT31 library for SHT30 models.
Q: Can I waterproof this?
A: The sensor element is exposed, so direct water contact is not recommended.
Q: Does this work with 5V logic?
A: Yes, it supports 3.3V to 5V input.
Q: What is the difference between DHT11 and SHT40?
A: SHT40 offers higher accuracy and faster response time.
Q: Is the cable included?
A: No, this listing is for the module only. Jumper wires sold separately.
