This is the new, weather resistant, field-hardened WR1 from Maxbotix
. The WR1 uses a robust PVC housing, is designed to meet IP67 water intrusion, and matches standard electrical 3/4" PVC pipe fittings. We are extremely pleased with the size, quality, and ease of use of this low voltage weather-resistant range finder. The serial interface is a bit odd (it's RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 254 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!
Maxbotix is offering the EZ0, EZ1, EZ2, EZ3, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Please see beam width explanation below.
Control up to 10 sensors with only two pins! Checkout the Maxbotix FAQ listed below.
