- Humidity and Temperature Specifications
3.1 Humidity Sensor Specification
Table 3. Humidity Sensor Specification, TA = +25°C, VDD = 2.3V to 5.5V
- Monotonic increases from 10 to 90%RH after sensor has been stabilized at 50% RH.
- Initial value to 63% of total variation.
3.2 Temperature Sensor Specification
Table 4. Temperature Sensor Specification, TA = +25°C, VDD = 2.3V to 5.5V Response Time Constant[ 1] (τT) - 2..0 - - Sec.
- Response time depends on system thermal mass and air flow.
- Temperature accuracy can be optimized for specified supply voltages upon request.
3.3 Sleep Current

- Typical Performance Graphs
4.1 Humidity Sensor Accuracy Graphs
The typical and maximum relative humidity sensor accuracy tolerances are shown in the following figures. Figure 4. HS3101-MCx RH Accuracy Tolerance at 25°C Figure 5. HS3101-MCx RH Accuracy over Temperature Figure 6. HS3103-MCx RH Accuracy Tolerance at 25°C Figure 7. HS3103-MCx RH Accuracy over Temperature
4.2 Temperature Sensor Accuracy Graphs
The typical and maximum temperature sensor accuracy tolerances are shown in the following figures. Figure 8. HS3101-MCx Temperature Sensor Accuracy Figure 9. HS3103-MCx Temperature Sensor Accuracy
share the bus; however only one master device can be present on the line.
5.1 I2C Features and Timing
terminated when the master sends a 1 STOP bit (P). These bits are only transmitted while the SCL line is HIGH. Figure 10. Timing Diagram Table 5. I2C Timing Parameters
- The minimum frequency of 20kHz applies to test only; no minimum under normal operations.
- Combined LOW and HIGH widths must equal or exceed the minimum SCL period.
5.2 Sensor Slave Address
5.3 I2C Communication
remain stable while SCL is HIGH to prevent false START or STOP conditions. Figure 11. START and STOP Condition Waveform bit is set to 1 to indicate a read from slave to master or set to 0 to indicate a write from master to slave. All transfers consist of 8 bits and a response bit: 0 for Acknowledge (ACK) or 1 for Not Acknowledge (NACK).
5.4 Measurement Mode
receives a Measurement Request command (MR); otherwise, it is always powered down.
5.5 Measurement Requests (MR)
Request by sending the 7-bit slave address followed by an eighth bit = 0 (WRITE). The output is always scaled to 14 bits. The order of the bits is big-endian.
Figure 12. Measurement Request
5.6 Data Fetch (DF)
a slave sends an acknowledge (ACK) indicating success. terminated by sending a NACK after the second byte. measurement times in 3 should be used, along with the 0.1ms wake-up time. RH+T measurement times (including wake-up time) at different resolution settings.
- Same resolutions are assumed for both relative humidity and temperature.
Figure 13. Data Fetch
5.7 Status Bits
are the status bits (see the following table). Table 6. Status Bits 00B Valid Data: Data that has not been fetched since the last measurement cycle. Stale Data: Data that has already been fetched since the last measurement cycle. status will be returned, but this data is actually invalid since the first measurement has not been completed.
5.8 Accessing the Non-volatile Memory
send the I2C address and a Write bit followed by the command 0xA0|0x00|0x00. Figure 14. Sequence of Commands to Enter Programming Mode
0 A 15
0 A 14 1315 1112 10 89 A 6 57 34 2 A1 0 1
listed in the following table. All of these registers are 16 bits wide. Write bit, followed by the command: 0x80|0x00|0x00. Table 7. Non-volatile Memory Registers 0x06 Humidity Sensor Resolution – Read Register (bits 11:10). 0x46 Humidity Sensor Resolution – Write Register (bits 11:10). 0x11 Temperature Sensor Resolution – Read Register (bits 11:10). 0x51 Temperature Sensor Resolution – Write Register (bits 11:10). 0x1E Read Sensor ID – Upper 2 bytes. 0x1F Read Sensor ID – Lower 2 bytes.
5.9 Setting the Measurement Resolution
changed to set the desired resolution, the entire register must be written back to the HS310x-MCx sensor. Figure 15. Sequence of Commands to Change the Relative Humidity Resolution
Table 8. Register Values for Different Resolution Settings address in Step 4 will be 0x51.
5.10 Reading the HS310x-MCx ID Number
16 bits stored in register addresses 0x1E and 0x1F, respectively.

Figure 16. HS310x-MCx Application Circuit Avoid using polyethylene antistatic bags as they may affect sensor accuracy.
- Bake at a temperature of 100°C with a humidity < 10% RH for 10 to 12 hours.
- Rehydrate the sensor at a humidity of 75% RH and a temperature between 20°C to 30°C for 12 to 14 hours.
