We are reading temperatures in silos (bins) mainly with grain but also animal food or other sensitive to heat products. It's 10-90 meter silos with 1-12 cables in each and 1-20 silos and 4-16 sensors per cable. Biggest system as per now is 20 silos, 240 cables and 2400 sensors. All connected with about 8.5km of wire. Just changing from PIC16 to LPC2138 as "heart" of the system. Spent some days just going thrue all data sheets and sometime you just loose focus, as with the UART, to find all specifications and values.
