Tessel Driver for Grove Ultrasonic Ranger v1.0 (SEN10737P)

This package allows the use on the Grove Ultrasonic Ranger v1.0 (SEN10737P) sensor on the Tessel board.

Usage

Using the package is easy. Just download and install it via NPM.

npm install tessel-sen10737p --save

Once the package is downloaded and installed, you need to get a reference to a pin on the Tessel that supports reading a PWM pulse. The driver has been tested using the G3 pin on the GPIO port.

// Load modules.
var tessel = require('tessel');
var sen10737p = require('tessel-sen10737p');

// Select a pin that supports reading a PWM pulse.
var gpio = tessel.port['GPIO'];
var pin = gpio.pin['G3'];

// Get a ranger which is bound to the PWM capable pin.
var ranger = sen10737p.use(pin);

// Call getDistance passing in a callback
ranger.getDistance(function (err, distance) {
    if (err) {
      console.log(err);
      return;
    }

    console.log(distance);
  });
};

Wiring

According to the Seeed Studio wiki, the SEN10737P supports both 3.3V and 5V power source. This means that you can wire-up the sensor directly to the Tessel assuming you are running it from the 3.3V power source. However if you are running from a 5V source you will need to step down the voltage.

The G3 pin on your Tessel's GPIO port supports the underlying readPulse(...) method that this library uses. Give it a try and if you encounter any problems post an issue or hit the Tessel forums.
