Budget: 5000 UAH Deadline: 20 days
I have experience working with street sensors. As for the controller, it is needed for environmental analysis. I can design and manufacture a prototype.
Project Description:
We are developing an innovative voice navigation project UGuider. It is necessary to create an autonomous audio module that automatically plays an MP3 file when the motion sensor is triggered. The device will be installed in open spaces (street locations, memorials, tourist points) and will operate from a solar panel without connection to the power grid.
Executor's Task:
It is necessary to:
Select optimal components (solar panel, battery, MP3 module, motion sensor, amplifier, charge controller).
Develop a connection scheme.
Assemble a prototype of the device.
Ensure stable operation at temperatures up to –20°C.
Configure automatic audio playback upon motion detection.
If possible — ensure minimal energy consumption for autonomous operation.
Expected Result:
A ready working prototype that:
operates autonomously from a solar panel
plays audio upon motion detection
works stably outdoors
requires no constant maintenance
Will be an advantage:
experience with Arduino / ESP32 / embedded systems
experience in creating autonomous solar devices
experience with audio modules (DFPlayer or similar)

Hello
Ready to execute.
I have significant experience in your field.
I will create a ready prototype.
All components are available.

We will discuss
UPD: a combination with a wind generator can be made. For autonomy.
Budget: 5000 UAH Deadline: 15 days
No microcontroller is needed here, we just need to determine how many messages per day are required and what their duration will be, as well as the power of the speaker. For -20 with a battery, it will be difficult, the rest is minor details.
