⚠️The device is not waterproof. For outdoor use or indoor environment with a constant 90% or higher humidity, please use a waterproof case and connect an external probe.

Connection of optional external sensors

Apart from temperature, humidity and lighting sensors WS1 Pro device has two USB ports, to which additional probes with RS485 interface can be connected, such as air temperature and humidity sensor TH30S-B, soil temperature and humidity sensor, temperature sensor PT-100 (-200°C to +400°C). However, only one probe of a given type can be connected at a time. The device supports two DS18B20 probes, which can be connected simultaneously using a USB splitter.
