I am studying the option to use a Mi-Fi in order to set low-cost sensors in places where there is no Wi-Fi.
I was wondering :
- if anyone could recomment a cheap 4G Wi-Fi hotspot equipment
- if anyone could tell me which amount of data I should buy in order to send PM1, PM2.5, PM10, HR and temperature measurements every 2mn30. I have no idea bout this.
Many thanks for your support,
