Frequently Asked Questions

Q: What is the difference between the SHT20 and SHT25 sensor modules?

A: Both the SHT20 and SHT25 are digital temperature and humidity sensors from Sensirion using the I²C interface. The SHT25 offers slightly higher measurement accuracy compared to the SHT20, making it better suited for applications where precision is critical. Both are compatible with the same wiring and code, so you can easily upgrade between them.

Q: Which microcontrollers are compatible with this sensor module?

A: This SHT20/SHT25 module is compatible with a wide range of microcontrollers including Arduino (Uno, Nano, Mega), Raspberry Pi, ESP8266, ESP32, STM32, and other platforms that support I²C communication. Libraries are readily available for all major platforms.

Q: What operating voltage does this sensor module require?

A: The module operates on a supply voltage of 2.8V to 6V, making it flexible enough to work with both 3.3V and 5V development boards without needing a voltage regulator.

Q: Can this sensor be used outdoors or in high-humidity environments?

A: The SHT20/SHT25 sensor supports a relative humidity range of 0–100% RH, making it suitable for high-humidity conditions. However, direct water exposure is not recommended. For outdoor use, it is advisable to house the module in an appropriate weatherproof enclosure.
