Hi, I have a small sailing boat which is moored in the middle of an harbour. I would like to monitor using GPRS 2G network (via Telegram) or SMS the following itens: -gps position. -temperature and humidity using the Dht11 sensor. -battery voltage. -water on the bilges. I would need also alerts for low voltage on the boat battery or high bilge water level. I have been successful in measuring the Dht11 output using WiFi and the following tutorial: [login to view URL] However can't do it using WiFi. I'm using the TTGO T-Call V1.3 ESP32 sim800l board and dht11 sensor. Would like to continue to use the same hardware in the project. Could you please provide me a quote for the development of the code? Best Regards

Hi, I am an Embedded System Developer. I have good experience of working on ESP32 based applications design. I can write firmware and ensure its stability of operation. The common maximum timeline for such project is 45 days. We can put the sensor data and GPS data to cloud using MQTT or HTTP/S requests. WiFi connectivity and other settings will be made configurable. We will create a deploy-able product out of this. Also we provide PCB development assistance to. Let us know your budget and work you expect out of this project. Thank you.

Dear Sir, Regarding the setup for GPS, it is recommended to utilize the Neo-6m GPS module and connect it to the TTGO module via UART for optimal performance. For the measurement of temperature and humidity, it is noted that you are already in possession of the DHT11 sensor. To monitor battery voltage, it is suggested to utilize a voltage divider in conjunction with a Zener diode to achieve accurate readings. Regarding water level measurement, if the goal is simply to receive an alert when water levels are high, a proximity sensor may suffice. However, a floater would be the ideal solution for accurate water level monitoring. For SMS alerts, the Sim800L is a reliable option. If Telegram alerts are desired, an alternative approach involves receiving the SMS message on another TTGO device with WiFi capabilities, which can then send the corresponding Telegram alert. Please let me know if you require further assistance or have any additional inquiries. Thank you for your consideration. Best regards, Pathum

Hi, I can provide a program with following features 1: Monitor temperature, humidity, gps position and water presence and trigger events based on configuration 2: Send alert over SMS/Call 3: SIM800 is capable of storing small voice clips and playback over call. It also support DTMF. So a simple IVRS to check status/configure device 4: A web interface to configure device over WiFi in AP mode

Hi, IMHO the only way to meet your goal is to actually build a prototype, so I have to buy the very same HW you're using. I did several remote management systems based on GPRSes, so I think I'll be able to to it and I can tell for sure that if you don't build it you'll likely experience issues. I will not ask to be paid until the PJ is finished and the specs met, however I Ask you to anticipate the expenses for the components. If you like pls. contact me in chat to iron the details. Cheers, Alex.

Hi, if there is no wifi then we dont need to use esp32. we can use arduino nano with gsm sim900d or sim900A. this way it will consume less power. we can sleep the controller when we dont need to send sms. i have already worked on such project where i had build gps location tracker that was sending location to server after 10seconds. Lets discuss budget as the mentioned budget is not acceptable.
