Wifi IOT Device: Hardware-Software Solution
Budget: $30 – $250 USD
I am looking for an IoT expert to develop a low-cost hardware-firmware solution for a remote proximity sensor monitoring.
The solution should handle digital input from PNP or NPN proximity sensors.
The hardware should include an onboard SD card for local data storage.
The firmware needs to be reliable for continuous sensor data reading and uploading on cloud.
