System for collecting the amount of rain per day via gsm. The system consists of a project in which the system is all the time sleeping and counting the pulses of the rain gauge, since this works using the Hall effect at the end of the day the system sends to a served the ubidots the value collected of pulses and with confirmation And the value of the battery charge. The system will need to develop a pcb board with the company logo Ads corp to the components where you can connect the sim800l and input to the battery connector and connect the rain gauge both connectors post. I need it to be a rechargeable battery so that the charge can power the system for at least 3 months on the 3.7 volt battery. I need you to have a 3 and 5 volt input on the board in case you change the rain gauge. Summarizing what will be developed. Printed circuit Code; Code with verification that the rain gauge and battery charge data were sent 4 times a day; And hosting this data on the ubidots server;
