# Handling Lipo Sensor Data With OpenTx 2.2 it is possible to have multiple Lipo sensors, each with a user-assigned name. The call to getValue() returns a table with the current voltage of each of the cells it is monitoring. This example demonstrates getting Lipo cell voltage from a sensor with the default name of 'Cels' #####Example: ```lua local cellValue = "unknown" local cellResult = nil local cellID = nil local function getTelemetryId(name) field = getFieldInfo(name) if field then return field.id else return -1 end end local function init() cellId = getTelemetryId("Cels") end local function background() cellResult = getValue(cellId) if (type(cellResult) == "table") then cellValue = "" for i, v in ipairs(cellResult) do cellValue = cellValue .. i .. ": " .. v .. " " end else cellValue = "telemetry not available" end end local function run(e) background() lcd.clear() lcd.drawText(1,1,"OpenTX 2.2 cell voltage example",0) lcd.drawText(1,11,"Cels:", 0) lcd.drawText(lcd.getLastPos()+2,11,cellValue,0) end return{init=init,run=run,background=background} ```
