Fun ESP-32 Project with Push Notification


I’m currently using an esp07-slave triggered by an event that sends a message to the esp12-master. The esp12 then directs the ardunio to turn-off a solenoid & sends push notification to the app. The arduino also supports an HC-05 module linked to the android app. The simple app can open or close the solenoid. Arduino also uses a manual push button momentary switch to open or close the solenoid.


This project is to simplify the earlier project without losing any of the functionality. This projects will eliminate the arduino, esp12, and the HC-05. Instead use the esp32 to perform the same tasks.

1). Would need to parse and plug my sketches into to esp32.

2). Enable the esp32 temperature function. Send the readings to my app. Trigger the solenoid closed at xF/C temp reading.

Brief description: (esp07- Slave function)

Multiple Slave esp07s if triggered sends message to esp32 master to close solenoid & send push notification message. The esp07 should not consume any current unless sending the message. The mechanical trigger switch also provides the voltage to power up the esp-07. "turns-on" the esp07 to send the message. Note: The esp07's aren't in a sleep mode. They are turned off unless turned on by the Mechanical trigger switch. Green led is (ON) when slave is in triggered state. When slave is out of triggered state led is (OFF). When slave is powered up the first time green led blinks (3) times.

Brief description: (esp32- Master function)

The master esp32 when triggered by the slave closes the solenoid and sends push notification to app. The esp32 can open or close the solenoid by manual momentary switch. This event also sends the push notification. The app can open or close the solenoid. The esp32 temp reading can trigger the solenoid closed & send push notification. When solenoid is closed red led is (ON). When solenoid is open green led is (ON), red led is (OFF). When esp32 receives message from esp07 Green led blinks (5) times. When esp32 is powered up for the first time green led blinks (3) times, then all led’s are off.

Hardware components:


1. esp07

2. led

3. switch- 2 wire probes

4. 3volt 230mh battery


1. esp32

2. 2 leds

3. Manual reset button

4. H-bridge

5. Solenoid

6. Temp probe

7. 3.3v power supply


Should be able to demonstrate by short video clip that the esp07 communicates with the esp32 as described.
