ESP8266 x 2 : This idea is intended to accompany the approach of the municipal garbage collection vehicle using radio communication systems in the 2.4 GHZ (Wifi) range.

sorry if the translation was not good. I used internet translator

It uses a medium distance receiver / detector in the residence or company whose function is to identify the approach of the vehicle in motion. It does not need an internet connection or the home's Wifi network. Average range of 100 meters. It makes it possible to index the vehicles along the avenues / streets that pass to confirm which one serves you. Example: VEHICLE 001 (streets A, B, C, D, E, etc.), VEHICLE 002 (streets X, Y, Z, W, etc.). IMPORTANT: Authorization with the company responsible for collection is required to install the transmitter using the 12/24 VDC vehicle power (battery). This detection (within the truck's range) is reported at the residence by: • Electronic system with audible warning (ESP32 / 8266 and buzzer). • Visual and audible warning on the cell phone (Android application). • Website with attention and audible warnings. • Possibility to automate dumpsters with covers to unlock and open when the truck arrives.

BENEFITS: Avoid permanence of packages left in the dumps or on the sidewalk in order to avoid: • Damage and vandalism by animals and garbage collectors. • Insect and rat infestation. • Alteration of the appearance of the facade of the property outside the collection hours. • Leaks and miscellaneous remains on the sidewalk.

The ESP8266 TRANSMITTER (truck) is looking for a host (SSID with defined name - WiFi 2.4GHZ) and when it enters the radio frequency range, it sends a pre-determined code to this host (RECEIVER in house). The ESP8266 RECEIVER connects to the TRANSMITTER, receives this code and performs an action (activates relay, blows horn, flashes light, etc.) until the RF signal is out of range.
