Overview
The WXT536 is a solid-state, all-in-one weather instrument that measures wind speed and direction, precipitation, barometric pressure, temperature and relative humidity. Its small size makes it ideal for quick, short-term deployments. However, the WXT536 is not intended for weather stations that require research-grade performance.

Technical Description
The WXT536's wind sensor consists of three equally spaced transducers that produce ultrasonic signals. Wind speed and direction are determined by measuring the time it takes for the ultrasonic signal of one transducer to travel to the other transducers.
Precipitation is measured one raindrop at a time. Whenever a raindrop hits the precipitation sensor, an electrical signal is produced that is proportional to the volume of the drop.
The WXT536 has a PTU module that contains a capacitive silicon BAROCAP sensor for barometric pressure measurements, a capacitive ceramic THERMOCAP sensor for air temperature measurements, and a capacitive thin film polymer HUMICAP180 sensor for relative humidity measurements. The PTU is housed in a naturally-aspirated radiation shield that protects it and reflects solar radiation.

Additional Compatibility Information
Mounting
The WXT536 is shipped with a mounting tube. The mounting tube fastens to a CM202, CM204, or CM206 crossarm via the CM220 Right Angle Mounting Bracket or 17953 1-in x 1-in NU-RAIL Fitting.
The 212792 is an optional mounting kit for the WXT536. It provides better water protection. When using the 212792, the WXT536’s IP classification is IP66; otherwise its classification is IP65. The 212792 fastens to a crossarm via the CM220 bracket or 17953 NU-RAIL fitting.
Bird Spike Kit
The 212793 Bird Spike Kit is used to discourage birds from roosting on the WXT536. This kit is fastened on top of the WXT536. It consists of a metallic band with spikes pointing upward. The spike’s shape and location ensure minimal interference of wind and rain measurements. The spikes are designed not to hurt the birds. Please note that when the kit is attached to the WXT536, more snow can accumulate on the WXT536, and the snow may melt slower.
