HRLV-MaxSonar-EZ MB1013 Ultrasonic Distance Sensor
High-resolution ultrasonic sensor with 1 mm accuracy and temperature compensation. Supports analog, RS232, TTL, and pulse width outputs; low power consumption.
Pinout
- TEMP1
Pin 1 temperature sensor connection for optional HR-MaxTemp external temperature sensor; leave unconnected when not used, per MaxBotix HRLV-MaxSonar-EZ datasheet.
Type · Signal - PW2
Pin 2 pulse-width distance output, 1 microsecond per mm, with 300 us to 5000 us output range for 300 mm to 5000 mm, per datasheet.
Type · SignalVoltage · logic output referenced to sensor Vcc/GND - AN3
Pin 3 analog voltage distance output, scaled at Vcc/1024 per 5 mm and referenced to GND pin 7, per datasheet.
Type · AnalogVoltage · 0 V at power-up; distance voltage depends on Vcc, about 293 mV to 4.885 V for 300 mm to 5000 mm when powered at 5 V - RX4
Pin 4 ranging start/stop input; internally pulled high. Hold low to stop ranging, bring high for 20 us or longer to command a range reading, per datasheet.
Type · UARTVoltage · logic input referenced to sensor Vcc/GND - TX5
Pin 5 serial range output. Default is RS232-format 0 to Vcc; TTL output requires soldering the TTL jumper pads. 9600 baud, 8N1, per datasheet.
Type · UARTVoltage · 0 to Vcc serial output by default; TTL option via jumper - V+6
Pin 6 positive power input, Vcc, per datasheet.
Type · PowerVoltage · 2.5 V to 5.5 V DC - GND7
Pin 7 sensor ground, DC return and circuit common ground, per datasheet.
