- Temperature sensor accuracy: ±0.2 °C typical (-10 °C to +80 °C)
- 14-bit resolution: 0.01% RH (typical)
- Low power consumption: 1.0µA average (one RH+T measurement per second, 8-bit resolution, 1.8V supply)
- Extended supply voltage: 2.3V to 5.5V
Description
The HS3001 is a highly accurate, fully calibrated relative humidity and temperature sensor. The high accuracy, fast measurement response time, and long-term stability, along with the small package size, make the HS3001 ideal for a wide number of applications from portable to harsh environments.
An integrated calibration and temperature compensation logic provides fully corrected RH and T values via a standard I²C output. The measured data is internally corrected and compensated for accurate operation over a wide range of temperature and humidity levels–user calibration is not required.

HS3001: sensor stuck providing stale data : difficult to reproduce failure modeProblemDetailsHypotheses Questions
... initiating a Measurement Request to the HS3001 and before the first Data Fetch. Instead, the MCU issues Data Fetches to poll the status of the HS3001. Each Data Fetch takes ~760 µs to complete, as shown below. Therefore, the HS3001 status should indicate valid data within 45 Data Fetch polling ...

HS3001 cannot get humidity value
Hi Renesas team and everyone, I am using the CK RA6M5 kit to program the HS3001 sensor. I am configuring registers to control the I2C peripheral and receive data from the HS3001 sensor. However, I am having an issue when reading the humidity value. While the temperature value changes continuously ...
