CT10
Grove connectable magnet sensor.
wired(obniz, { signal [, vcc, gnd]});
| name | type | required | default | description |
|---|---|---|---|---|
| signal | number(obniz Board io) |
yes | Signal pin of state output(4 pin of Grove) | |
| vcc | number(obniz Board io) |
no | VCC for ct10(2 pin of Grove) | |
| gnd | number(obniz Board io) |
no | GND for ct10(0 pin of Grove) |
// Javascript Example
var ct10 = obniz.wired("CT10", {gnd:0, vcc:1, signal: 3});
ct10.onchange = function(voltage) {
console.log(voltage);
}
onchange = function(detect){}
called when ct10 detect/miss magnet field.
// Javascript Example
var ct10 = obniz.wired("CT10", {gnd:0, vcc:1, signal: 3});
ct10.onchange = function(detect){
console.log("magnet field detect:" + detect)
};
[await] isNearWait()
Check if powerful magnet field exist or not.
// Javascript Example
var ct10 = obniz.wired("CT10", {gnd:0, vcc:1, signal: 3});
var detect = await ct10.isNearWait();
console.log("exist = " + detect);
[await] stateWait()
Wait until state change.
// Javascript Example
var ct10 = obniz.wired("CT10", {gnd:0, vcc:1, signal: 3});
await ct10.stateWait(true);
console.log("ct10 detect magnet field!");
await ct10.stateWait(false);
console.log("ct10 miss magnet field");
Supported from: obniz.js 3.5.0
