work with Arduino? Does anybody has an idea how it works and how it could be integrated with arduino? Or do I need the electronic module that comes with it?
Here's some technical info on the item:
Center frequency (KHz): 40±1.0KHz Echo Sensitivity: ≥200mV Decay Time: ≤1.2ms Directivity (deg ) X-axis: 60±15 Directivity (deg ) Y-axis: 60±15 Capacitance ( pF ): 2000±15% Allowable Maximum Input Voltage ( Vp-p): 140 (40KHz) Pulse width 0.5ms, interval 20ms Mean Time to Failure: 5000h Operating Temperature ( Degree Celsius ): -40~+80 Storage Temperature ( Degree Celsius ): -40~+80 Cable Length: 250 cm Radar Diameter: 22.5 mm
