ECOWITT WH90LP Wireless Weather Stations Unit Modbus RS485 Cable Version, 7 in 1 Professional Wifi Outdoor Sensor of Weather Station for Designed Programming Only

• Note- We recommend using lithium batteries in cold climates. Avoid using alkaline batteries, especially in cold, damp conditions when starting internal heaters, as heat buildup can cause alkaline batteries to leak when temperatures exceed certain limits.
• - You can install a pole (not included) on a permanent structure and then mount the sensor kit on the pole. - The mounting hole accommodates a pole with a diameter of 1.0 inches (pole not included).
• This RS485 product requires a wired connection to the host. Please note that we do not currently offer a wireless console that supports the RS485 interface sensor. Users need to use RS485 wired connections to enable communication and data transfer between the sensor and the host.
• 7 in 1 Weather Station Unit: The WH90LP Outdoor Sensor comes with Modbus RS485 cable version, offers ports to enable programmers to program themselves, and is the only product on the market that offers programmers a way to play with their hobby.
