Frequently Asked Questions

What is the wiring configuration for the 4-20mA output?

The sensor uses a two-wire current loop. Connect the positive power supply (12-24V DC) to the sensor's positive terminal. The sensor's negative terminal provides the 4-20mA output signal and must be connected to the positive input of your current-reading device (PLC analog input, data logger), with that device's negative input returning to the power supply negative. Always use shielded, twisted pair cable for best noise immunity.

Can this sensor be used outdoors?

While the sensor operates from -10°C to 60°C and tolerates 0-80% RH, it is not rated as waterproof (IP-rated). For outdoor use, it must be installed in a fully sealed and protected enclosure or junction box to prevent direct exposure to rain, snow, and condensation, which would damage the electronics.

How do I convert the 4-20mA signal to a Lux value?

The output is linear. 4mA corresponds to 0 Lux, and 20mA corresponds to the full-scale value of 200,000 Lux. Use the formula: Lux = ((Measured Current in mA - 4) / 16) * 200,000. Most PLCs and data acquisition systems have built-in scaling functions to perform this calculation automatically after you configure the input channel for a 4-20mA signal.

What is the power supply requirement?

The sensor requires a 12-24V DC power supply. Ensure your power source can provide sufficient current, as the loop requires up to 1000 mA to drive the 20mA signal through the load resistance of your receiving device. The optional 230V AC operation typically requires an external AC/DC power adapter.
