Frequently Asked Questions

What is the operating voltage range for the Renke SHT-71 probe?

The probe operates from 2.4V to 5.5V DC, making it directly compatible with both 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi without requiring a logic level shifter.

How do I communicate with this sensor, and what is the pinout?

Communication is via the standard I2C protocol. The cable typically includes four wires: VCC (2.4-5.5V), GND, SDA (data), and SCL (clock). The sensor supports I2C speeds up to 1 MHz and uses the default SHT35 I2C address.

What is the typical accuracy of the temperature and humidity readings?

The integrated Sensirion SHT35 sensor provides high typical accuracy of ±0.1°C for temperature and ±1.5% relative humidity (RH). Note that these are typical values; for specific tolerance bands, refer to the SHT35 datasheet.

Can this probe be used outdoors or in harsh environments?

Yes, its stainless steel probe construction and wide operating temperature range of -40°C to +125°C make it suitable for demanding environments. However, the exposed electronics at the cable end should be protected from direct moisture or condensation.

Is the sensor calibrated, and does it require periodic recalibration?

The SHT35 chip is factory calibrated, providing fully calibrated digital output. It exhibits excellent long-term stability and generally does not require user recalibration under normal operating conditions.
