Frequently Asked Questions

What is the operating voltage range for the SHT30-ARP-B2.5KS?

The sensor operates from 2.15V to 5.5V DC, making it compatible with both 3.3V and 5V logic systems commonly found in Arduino, Raspberry Pi, ESP32, and other microcontroller platforms.

What is the communication protocol and maximum speed?

It uses a standard I2C (2-wire) interface. The communication speed can be configured up to 1 MHz (Fast Mode Plus), allowing for high-speed data acquisition in demanding applications.

How accurate is the sensor and does it require calibration?

The sensor offers typical accuracies of ±2% RH for humidity and ±0.2°C for temperature. It is fully factory calibrated and temperature compensated, so no user calibration is required for most applications.

What is the power consumption in different modes?

Power consumption is optimized for battery life. During measurement, it draws approximately 300 µA. In sleep (idle) mode, consumption drops to just 0.4 µA, enabling long-term operation in power-constrained IoT devices.
