I've seen tanks overflowing which is a waste of water and hence decided make this prototype.
Automatic maintaining of water level via Python program:
Controlling pump via Alexa:
Web page to view water level and control the pump:
Python program for automatic water level control
PythonRunning the following code will check water level every 10 seconds and display it. If the water level is below 20%, pump is switched ON and when it reaches 100% the pump is switched OFF.
import json,time,requests
from boltiot import Bolt
mybolt = Bolt("API Key","Device ID")
while True:
response = requests.request("GET","https://cloud.boltiot.com/remote/API Key/serialWR?data=getAnalogValues&deviceName=Device ID")
data = json.loads(response.text)
csv = data["value"]
temp = csv.split(",")
arr=[]
for i in range(len(temp)-1):
arr.append(int(temp[i]))
print(arr)
if arr[0] < 100:
print("Water Level below 20%. Turning pump on")
requests.request("GET","https://cloud.boltiot.com/remote/API Key/serialWR?data=pumpOn&deviceName=Device ID")
elif arr[4] > 100:
print("Water level 100%. Turning pump off")
requests.request("GET","https://cloud.boltiot.com/remote/API Key/serialWR?data=pumpOff&deviceName=Device ID")
else:
if arr[3] > 100:
print("Water level is at 80%")
elif arr[2] > 100:
print("Water level is at 60%")
elif arr[1] > 100:
print("Water level is at 40%")
elif arr[0] > 100:
print("Water level is at 20%")
else:
print("Error")
time.sleep(10)

To control pump via Alexa
XMLIn IFTTT, create two applets:
- One having Alexa trigger as "Pump on"
- And the other having "Pump Off"
- For "That" section, select Webhooks and insert the given urls respectively.
