Hello, I will use ESP8266/ESP32 (MCU with Wi-Fi, Arduino Compatible) as main Controller. For GSM & GPS module, I will use Adafruit Fona(SIM868 based), it's already has both GPS & 3G GSM features. battery will be Lithium Ion, and we can add a charging feature if you want. of course we will use DS1820 for sensor. I have been working with all of those stuff so I'm very confident this can be finished as soon as possible, might be less than 15 days(including shipping time). Just Let me know your server and proposed algorithm. We can discuss it over chat. I have 8 years experience in hardware design, firmware coding and Arduino. I have developed several GSM based monitoring system , So I'm familiar with several protocol, like MQTT,HTTP,UDP,TCP. let me know your thoughts about this proposal Best Regards Rijal

Hello, Using Arduino, would require a GSM/GPRS module such as SIM800, and for the GPS shield you could use Neo-6M for cheap. For the data send I think there are a few methods, you could use simple HTTP Post, a web service in xml format or json, or simply using MQTT protocol which is widely used in IoT data transaction such as RabbitMQ. Which one you will prefer?

Hi, You propose a very interesting project of which I would love to be a part. For my degree project I worked on a similar IOT device project focused on monitoring an array of 9 sensors including: Presence, humidity, temperature and intrusion. The device (NodeMCU ESP8266) communicated to a server using the MQTT protocol, which allowed to monitor and control the system remotely. I have advanced knowledge in C and C++ software development for Arduino, NodeMCU ESP8266, ESP32 and ARM microcontrollers. In addition, I have worked previously in projects for IoT, IoMT and digital signal processing applications using various communication protocols such as: SPI, I2C, USB, UART, MQTT, RS232 and ModBUS. Always with excellent results. Please contact me to discuss the details of your proyect. Bugs resolving cost are included in my bid amount. Looking foward to work with you. Best regards, Javier Inojosa.
