XL-MaxSonar-EZ0 MB1200 Ultrasonic Distance Sensor

The product is a compact ultrasonic sensor with a wide, sensitive beam for indoor use, offering reliable detection and real-time calibration. It operates on 3.3-5.5V.

Pin 1MB1200 datasheet pin 1
Leave open or high for serial output on Pin 5; hold low for Pin 5 pulse output suitable for low-noise chaining.
Type · controlVoltage · 0-Vcc logic, Vcc is 3.3V to 5V
PWMB1200 datasheet pin 2
Pulse-width range output on MB1200. Datasheet scale factor is 58 µs per cm.
Type · digital ioVoltage · 0-Vcc logic, Vcc is 3.3V to 5V
ANMB1200 datasheet pin 3
Analog voltage range output, scaling factor Vcc/1024 per cm. Buffered output for most recent range data.
Type · analogVoltage · Vcc/1024 per cm; about 4.9 mV/cm at 5V and 3.2 mV/cm at 3.3V
RXMB1200 datasheet pin 4
Ranging control input. Internally pulled high; left open or high keeps measuring, held low stops ranging. Bring high for 20 µs or more for a range reading.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.

Temp and humidity

DHT11, DHT22/AM2302, and DHT20/AHT20 sensors solve the same broad job, but only some are acceptable substitutes in the same circuit.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
