I need a Short Range RF Distance Sensor, with very narrow beam. Please see the attached drawing.
The sensor must be designed for operation in harsh environment, approx. -20*C to +30*C. The sensor will not be directly exposed to wind , rain or snow, but it must be able to withstand heavy moisture and condensation on the sensor-lens.
1). The maximum measured distance is 250mm. (not 175mm as indicated in the drawing).
2). The minimum measured distance is close to zero as possible.
3). the accuracy is approx. +- 3mm.
4). The price for the finished designed sensor-setup, should be as low as possible. Approx. 10USD
Optical sensors are not an option for the project.
