Hi all,
I just connected mi one wire to my grove + electron. All is working fine, but I want to connect another one to measure another part of the truck.
How could I connect and read the two sensors?
See attached my code to help.
Thank’s
Eduard
#include <ThingSpeak.h>
// This #include statement was automatically added by the Particle IDE.
#include <OneWire.h>
#include "DS18.h"
/* Thingspeak */
TCPClient client;
unsigned long myChannelNumber = *******;
const char * myWriteAPIKey = "********";
DS18 sensor(D4);
void setup() {
ThingSpeak.begin(client);
Serial.begin(9600);
// Set up 'power' pins, comment out if not used!
//pinMode(D4, OUTPUT);
//pinMode(D5, OUTPUT);
//digitalWrite(D4, LOW);
//digitalWrite(D5, HIGH);
delay(1000);
sensor.read();
Serial.printf("Temperature %.2f C", sensor.celsius());
//Serial.printf("Temperature %.2f C %.2f F ", sensor.celsius(), sensor.fahrenheit());
Serial.println();
Particle.publish("temperature", String(sensor.celsius()), PRIVATE);
//battery level
/*FuelGauge fuel;
float batt;
batt = fuel.getVCell();*/
// Update the 2 ThingSpeak fields with the new data
// ThingSpeak.setField(1, (float)device);
ThingSpeak.setField(2, (float)sensor.celsius());
/* ThingSpeak.setField(3, (float)humidity);
ThingSpeak.setField(4, (float)pressure);
ThingSpeak.setField(5, (float)batt);*/
// Write the fields that you've set all at once.
ThingSpeak.writeFields(myChannelNumber, myWriteAPIKey);
// Give time for the message to reach ThingSpeak
delay(5000);
// Sleep for 15 minutes to save battery
System.sleep(SLEEP_MODE_DEEP, 2 * 60);
}
void loop() {
}
