Hi all,
I'm new to the forum and very new to the world of electronics but fascinated by the IOT and what is possible today. I have a project in mind I'd be keen to get some advice on. I've had a search through the forum but couldn't find anything specifically related to what I want to do.
I have a house that is supplied by rainwater. The house is 200 km from where I live. The rainwater leg to the tank has a drain pipe on it with a flush valve to enable the roof and leg to be flushed so that the dirty water is not directed to the tank. The valve is a simple pull up domestic pvc water valve (approx 100mm stroke). I would like to be able to operate the valve remotely. My thinking is to use a linear actuator to open the valve with the actuation being activated by a phone call or sms. I would like the valve to operate in a cycle mode. That is, with the valve closed, receipt of sms starts opening. If no further sms is received, the valve opens to the open limit of the actuator. if a sms is received before this, the actuator stops in the current position. The next sms starts the actuator operating in the opposite direction (ie closing the valve). If no further sms is received, the actuator operates to its closed limit (valve closed). If an sms is received before this limit is reached, the actuator stops in current position etc. I have been looking at the concens actuators and control board (www.concens.com/) and cheap gsm units (http://www.imexbb.com/the-gsm-contr...control-swich-in-systemy-alarmow-11928505.htm) but I don't think this will manage the control I want. Perhaps it is an arduino project with the gsm shield to manage the sms.
I will also need the ability to calibrate the open and close limits on the actuator.
Any thoughts as to how I might achieve this would be gratefully received.
Cheers
Steve
