Why Choose the RFS300?
The RFS300 is a board-mount air velocity and temperature sensor that uses a reference design circuit for maximum positioning flexibility, thereby creating the smallest possible sensor footprint (6mm x 6mm). The RFS300 is designed to be soldered directly to a printed circuit board or mounted to a surface mount socket for easy removal or maintenance.
