Humidity and Temperature Sensor Breakout

The SparkFun HIH6130 breakout board combines a digital relative humidity and temperature sensor in one package. It provides true temperature-compensated I2C output for accurate environmental readings. Standard 0.1 inch spaced headers make prototyping straightforward. Basic soldering skills are required to attach headers.

Makers and developers adding environmental sensing

This board suits anyone building a humidity-sensing application who needs compensated digital data over I2C. It operates from 2.3 to 5.5 volts with a compensated humidity range of 10 to 90 percent RH and a temperature range of 5 to 50 degrees Celsius. Buyers who need analog output or a different communication protocol should look elsewhere.

Integrates via I2C into microcontroller projects

The breakout connects directly to a microcontroller using the I2C bus and standard libraries such as Wire.h. Its wide operating voltage range allows it to work with 3.3 volt or 5 volt logic without extra level shifting. The 0.1 inch pin spacing fits breadboards and perfboards, freeing up layout space for other components.

Questions about this item

What power supply range must my board provide for the HIH6130 breakout to operate?

The sensor operates from 2.3 to 5.5 V, so your host must supply a rail within that window.

Will the sensor still give compensated readings if my enclosure sees temperatures below 5 °C or above 50 °C?

Compensated humidity and temperature specifications cover 5–50 °C; outside that range the compensation accuracy is not guaranteed.

After wiring the I2C lines and powering the board, how can I confirm the HIH6130 is communicating correctly?

Scan the I2C bus for the device address; a successful response means the sensor is powered and the digital interface is active.
