The datalogger can be powered either by Lithium or Alkaline cells or by a 12V SMF battery chargeable from AC mains or solar panel. 2.3.2. Wireless monitoring system using radio frequency (RF) Dam monitoring sensors network with radio frequency (RF) communication does not require any cabling. It essentially comprises of sensors connected to RF dataloggers and gateways ( ) and features long-range communication on ISM frequency range of permitted in the country of use, of up to 15 km in open field conditions. The low power consumption of the system results in datalogger batteries lasting up to 5 years. Refer to Fig. 7 for a block diagram of a dam monitoring instruments network built on RF data communication technology. Fig. 6 Typical RF sensor network at field The RF dataloggers, often called the ‘nodes’ of the wireless network, can be easily configured in the field using the smartphone Android app provided. These are available in single and multichannel configurations suitable for 1307
