I need some help with a project for mu church and there might be some compensation available.
We have a failing well. We need to monitor the water flow and then text or email person(s) to let them know.
We have an electronic valve that I get 110vac when energized. I am using a cell charger to provide me 5vdc when water flows. I have built the circuit to provide a small dc voltage to the Arduino A0 input when the event occurs. I am not very good with coding and need to have a sketch with the following specs......
Start monitoring when A0 get a voltage...
Capture start time and end time
And evaluate if outside of normal hours
Evaluate if more than 4 hours
Room for me to add analysis
I think you will need an RTC, and some means to send your text/email or notify some other device to send the text/email on your behalf. You'd better decide how that side of things is going to be implemented at an early stage. For example, if the Arduino is going to be on its own you'll need to provide some sort of GSM modem or mobile data service, but if there is an internet connection available in the area then you would be better off looking for a way to access that.
Good Afternoon
I am trying to develop an Arduino applications to monitor water flow at our Church. We have a failing well and must be sure the water is not being used badly. We have a flow valve that presents 110vac to an extension cord every time there is flow. I have used an old Cell charger and am looking at the presence of +5vdc when the water flows.
I have built the circuit to give this voltage to the Arduino on Analog Pin #1. When it senses +5v the program needs to begin monitoring and look for a series of events.....
More than 4 hours of constant water flow
Any Water flow after normal hours (ability to set the hours)
I am not good with the C language. Would even consider paying someone to help me do this.
Getting a text message at 2:30 in the morning to come turn off the water, when the stupid computer could have done that instead, would have me kicking the thing all over the place.
It sounds to me that you really don't plan to put effort into learning this. If that is the case and you'd rather just pay to have it done then post it in the Gigs and Collaborations forum http://arduino.cc/forum/index.php/board,26.0.html
I just need to know how to make it send a message.
What "it" needs to send a message? There are services available, like usamobility.net that let you make a GET request with appropriate fields valued, that will then send a text message to the appropriate phone number(s).
I am trying to detect on an analog pin when there is 3 vdc present and then when it is 0. That is the event I need to monitor. Sit all the time looping until it senses a + voltage at an analog pin. Then start counting until the voltage goes to 0.
Can anyone help me with the actual coding? I am having some problems....
This is my attempt to read A0 and upon a voltage begin a loop
/ the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
int time=0;
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int accum;
accum=0;
int sensorValue = analogRead(A0); //Serial.println(sensorValue);
if (sensorValue<60)
{
Serial.println("flow=on");
Serial.println(sensorValue);
}
if (sensorValue>60)
{
Serial.println("flow off");
Serial.println(sensorValue);
}
//if (sensorValue>60)
//{
// Serial.println(
delay(1000); // delay in between reads for stability
Then I need to start counting when the flow = on and measure how long flow is on. and do some calculations. Then stop when flow=off.
Use a boolean variable to record whether flow is on or off. Set it in the ifs you're using to send messages about the flow state. Before you set it, check whether you're about to change its state. If you're about to turn on from off, record the start time using millis. If you're about to turn off from on, use millis and the start time to tell how long it was on. Do your calcs.
