Gravity: Science Data Acquisition (SCI DAQ) Module - Screen Display, Plug-and-play, Data Logging Spedizione:4-6 Giorni They can easily go 2

They can easily go 2 Km line of sight using simple wire antennas

but the fully packaged antennas have better strain relief where the SMA cable meets the antenna housing

it can be used for 868 MHz or 915 MHz (the radios use software configured frequency) These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit

* Ripple: 160mVp-p

DFRobot has provided users with hundreds of sensors of all kinds. However, many of them output raw electrical signals like current, voltage, etc., and to obtain data in standard units of physical quantities, users need to look for relevant information in the product datasheets and convert data by formulas or coding. Meanwhile, the data format varies with different sensors, so each sensor requires a specific control
