DESCRIPTION
WS3800- 7.5" LCD display & 8 physical buttons.
- Support DC powered and 3 x AA alkaline or lithium batteries powered (3 fresh AA batteries (not included) can run for 15-25 days. Only used as a short-term backup power).
- Supports monitoring indoor and outdoor conditions, it has built-in temperature, humidity, and barometric pressure sensors, and can connect almost all Ecowitt transmitters with the same RF frequency to use together, to get accurate weather data including wind speed, wind direction, rainfall, UV, solar radiation, outdoor temperature, outdoor humidity, dew point, feels like, CO2, PM1.0, PM2.5, PM10 and more.
- Sensor: Piezoelectric rain gauge; Ultrasonic wind speed, gust speed, and wind direction; Temperature; Humidity; Solar light intensity and UV index; Waterproof IPX5;
- The supply voltage range can only be 5~20V, more than that will be very dangerous and will cause damage to the WS90.
