Frequently asked questions
What do the ND codes mean?
The ND codes are our own product codes. Each product page lists what the sensor measures, its specifications and typical uses.
Which datalogger do the sensors connect to?
The product pages describe use with the yDoc ML-525 multipurpose datalogger, which sends data to Sensor-Online over HTTPS or MQTT.
Can I get sensors that are not listed?
Yes. Our online catalogue has more than 1,200 industrial and IoT sensors, and we can help you choose and connect them.
