Frequently Asked Questions

What is the output signal of this sensor and how do I interface it?

This sensor provides a 0-10V analog voltage output proportional to the measured temperature or humidity. You can connect it directly to any device with a high-impedance analog voltage input, such as a PLC analog module, data logger, or microcontroller ADC pin (using a voltage divider if the MCU is 3.3V or 5V). The output resolution is configurable for either 10-bit or 12-bit granularity.

What power supply does this module require?

The module operates from a 12-24V DC power supply. Ensure your power source is within this range and can provide sufficient current (typically less than 50mA). Connect the positive wire to the V+ terminal and the negative to the GND terminal on the board's screw terminal block.

How accurate are the temperature and humidity measurements?

The sensor utilizes an AHT20 chip, providing a temperature accuracy of ±0.3°C and a humidity accuracy of ±2% RH under typical conditions. Accuracy can be affected by extreme temperatures, airflow, and calibration; for highest precision, allow the sensor to stabilize in its environment.

Can this sensor be used outdoors?

Yes, its operating temperature range of -40°C to +85°C makes it suitable for outdoor applications. However, the PCB itself is not waterproof (IP-rated). For outdoor use, you must house the module in a protective, weatherproof enclosure that allows air circulation to the sensor element while preventing direct water ingress.
