Description

The Renke SHT-77 probe integrates the Sensirion SHT20 CMOSens® chip, which combines a capacitive polymer humidity sensor and a band-gap temperature sensor. This digital sensor provides fully calibrated, linearized signals via the I2C interface, eliminating the need for external signal conditioning. The extended 77mm PE-bodied probe allows for measurement points deeper within equipment or environmental chambers.

Designed for stability and long-term reliability, the SHT20 IC offers 14-bit resolution and fast response times. The probe is suited for continuous monitoring applications in industrial automation, HVAC system control, and data-logging environments where consistent, accurate data is critical.

Frequently Asked Questions

What is the operating voltage range for the Renke SHT-77 probe?

The Renke SHT-77 probe operates from 2.1V to 3.6V DC. It is designed for low-power applications and is compatible with standard 3.3V microcontroller logic levels, making it suitable for battery-powered or embedded systems without requiring a level shifter.

How do I interface the SHT-77 probe with an Arduino or Raspberry Pi?

The probe uses a standard I2C communication interface. Connect the probe's VCC (2.1-3.6V), GND, SDA, and SCL pins to the corresponding pins on your microcontroller. You can then use libraries designed for the Sensirion SHT2x family of sensors to read the calibrated digital temperature and humidity values.

What is the advantage of the 77mm probe length?

The extended 77mm length allows the sensing element to be positioned deeper into measurement environments, such as inside air ducts, machinery housings, or process vessels. This provides a more representative measurement of the core environment compared to surface-mounted sensors, improving system control accuracy.

Does the SHT-77 probe require calibration?

No, the integrated Sensirion SHT20 sensor is factory-calibrated. It outputs fully calibrated digital values for temperature and humidity directly via the I2C interface, providing plug-and-play accuracy without requiring user-level calibration in most applications.
