Today we'll discuss about the GPRS modem, or rather, the ESP32 and its use with the cellular telephone network. This is something that works very well. Using the MQTT protocol, we will then send data to the Ubidots dashboard. Use in this assembly a display for feedback of the circuit, in addition to the SIM800L and a cell phone chip.ESP32: SIM800L and Barrier Sensor: Today I’ll discuss an assembly that functions as an alarm and automation together, using the SIM800L. The modem is GPRS and needs a SIM card. We can say this is like a "cell phone," but it’s very cool. It’s extremely cheap and allows you t…

It is an upgraded version of T-Call V1.3: Change the power IC to AXP192 PMU management, support coulomb counter and high precision voltage and current Test function. SIM800L RI Pin leads to ESP32, can accept voice or data calls, Wake up from received message. The SIM800L DTR Pin leads to SP32, which can wake up SIMM800L from sleep state. a)enough for sim800l. b)low enough for arduino to not loose power. c)easy to operate also with esp32(in case someone wants esp32) d)Can operate safelly also at maximum of 10 Volts . But....in the case of LCD with I2C we need more volts
