I am doing research on Smart Agriculture where i am using MKR1000 with 2x Soil Moisture Sensors & 2x DS18B20 Temperature Probe with DHT22 for Temperature and Humidity Monitoring. Using Thingspeak Cloud for data storage and visualization. i am powering the Board with 5v Mobile Charger but after some time Orange Light starts blinking and MKR1000 stops sending data to cloud. any person who sorted out that issue?
I have the same issue where I connected my MKR1000 using the USB as a power source. After about one month, it stopped sending data to my Thingspeak channel.
I Think I may know the problem. I need to know how it is powered and the environment it is in. Also a schematic not a frizzy picture as how you have it wired including all power, ground connections. Posting your code may help but I am not sure at this point as it appears to work a long time. Does it start working after reset, power cycle?
