Algorithm
1 Procedure to read temperature from DHT11 Sensor.
| Step 1: start. | | Step 2: [check NodeMCU connection]. | | If(connected) { | | Read temperature of the user. | | } else { | | NodeMCU connection failed. | | } | | Step 3: [read the temperature]. | | Get data from DHT11 sensor. | | Step 4: send the temperature data to firebase real-time database. | | Step 5: display the data in user and admin android application. | | Step 6: check the data with applied conditions. | | Step 7: if (temperature > normal) { | | Buzzer = ON. | | Red LED = ON. | | Notify the user and admin. | | } else { | | Green LED = ON. | | } | | Step 8: repeat steps 3 to 7. | | Step 9: end. |
