Remotely controlled and monitored systems are becoming increasingly popular by the day. Smart automata, such as SMS vending machines or parking ticket payment stations became part of our everyday lives. We are presenting you with a fantastic and most useful project, which can have dozens of great applications. Using PICPLC4 v6, TelitGM862 GSM/GPRS module, Potentiometer Board, SHT1X Temperature and Humidity Sensor, and EasyInput Boards, we have created Smart SMS relay Control Station and an example which you can adjust according to your needs. What it does is basically this:

Smart SMS Relay Control Station Video

Video Demonstration

Watch on YouTube

Program is triggered by incoming SMS message. It sends information about current automata state, and can also be ordered to turn on/off four available relays.

  1. When system receives Status? SMS message it responds with complete status of 4 Relays, 4 Digital Inputs, 2 Analog Inputs, Current Temprature and Humidity information.
  2. R1ON message commands the board to turn on Relay1. You can also do this with other three relays: R2ON, R3ON, R4ON.
  3. R1OFF message commands the board to turn off Relay1. This also applies to other relays as well: R2OFF, R3OFF, R4OFF.
  4. An example of one control message is below: R1ON R2OFF R3ON R4OFF Status? (Note that there is no need for separaion chars, spaces in this case). Valid message is also: R1ONR2OFFR3ONR4OFFStatus? just be careful about the letter casing.

Applications

Project has numerous applications. We only suggest several:

  1. Building your own weather station with additional functions
  2. Making your SMS home automation and control systems
  3. Building your SMS vending machines
  4. Implementing automatic Parking management system

We are sure that you will find much more possible applications. Don’t hesitate to send us photos of what you have built using this project kit.

Source code of this project is provided for free, so you can modify it to suit your needs. Since PIC18F87J60 comes preprogrammed with free UART Bootloader, you won’t have to spend a dollar more on external programmers. You can use both on-board UART connector or additional USB-UART board if you do not have RS-232 connector available on your computer.

IrThermo 2 click

5

IrThermo 2 click carries the TMP007 infrared thermopile sensor with an integrated math engine. The measurement range of the sensor is between –40°C to 125°C (with a 14-bit resolution). IrThermo 2 click communicates with the target board MCU through mikroBUS I2C pins (SCL, SDA. The board is designed to use either a 3.3V or a 5V power supply.

Ozone 2 click

10

Ozone 2 click carries an MQ131 sensor for Ozone (O3). The sensor outputs an analog voltage, which is converted by the onboard MCP3551 22-bit ADC converter or it is sent to the microcontroller via AN pin on the mikroBUS™, depending on the position of ADC SEL. jumper. The click is designed to run on 5V power supply.
