Frequently Asked Questions

What is the supply voltage range for the Sharp Microelectronics QM1H0P0073 sensor?

The sensor operates from 2.7 to 5.5 volts DC. This wide range makes it directly compatible with both 3.3V and 5V microcontroller systems, such as Arduino, Raspberry Pi, ESP32, and STM32 boards, without requiring a level shifter.

Does this sensor require calibration before use?

No, the Sharp Microelectronics QM1H0P0073 is factory calibrated for both humidity and temperature. The calibration coefficients are stored on-chip, enabling plug-and-play operation without any additional user calibration steps upon installation.

What is the communication protocol and how do I connect it to my microcontroller?

It uses a standard I2C digital interface. Connection requires four wires: VCC (2.7-5.5V), GND, SDA (data), and SCL (clock). Pull-up resistors (typically 4.7kΩ) are recommended on the SDA and SCL lines if not provided by your host controller.

What is the typical accuracy and measurement range?

Typical accuracy is ±2% for relative humidity (0-100% RH range) and ±0.3°C for temperature (-20 to +85°C range). This high precision makes it suitable for demanding environmental monitoring applications.

Is this sensor suitable for battery-powered devices?

Yes, its ultra-low average current consumption of 3.0 µA (maximum) in non-operating state makes it ideal for battery-powered IoT nodes, portable loggers, and other power-sensitive applications where energy efficiency is critical.
