Aruduino+Blynk
Budget: $10 – $30 USD
The requirements of my project is IoT (blynk+arduino) and consists of below components:
a. PH sensor - can set a threshold value min & max value, if exceeds or below then notification trigger.
b. Water temp sensor - can set a threshold value, if exceeds value then trigger notification and turn on cooler fan relay ; if below then turn on heater relay.
c. TDS sendor - can set a threshold value min & max value, if exceeds or below then notification trigger.
d. Ultrasonic sensor for plant - can set a value if exceed then trigger notification.
e. Ultrasonic sensor for water - can set a value if lower then trigger notification.
f. Relay for Water pump and air pump is always on.
g. Water flow sensor - set a default value if lower then notification trigger.
h. Digital light sensor - set a default value, if lower then turn on grow light relay.
i. Servo motor is for fish feeder, presh button then servo motor move.
