steps for checking data

[joeyklee]

Checking Data

1. turn off system
2. remove microSD --> insert microSD into card adapter --> insert into computer
3. Go to latest data folder: YYMMDD
4. Open any file in excel, matlab, R, etc...
5. column headers are as follows:

date,time,gpsFix,gpsQuality,latitude,longitude,speed,elev,gpsSat,t_therm,hum_dht22,t_dht22,iramb,irobj

a sample looks like this:

date,time,gpsFix,gpsQuality,latitude,longitude,speed,elev,gpsSat,t_therm,hum_dht22,t_dht22,iramb,irobj
17/08/2016,21:00:00.000,1,1,  49.26161,-123.25105,0.72228,114.00000, 8,22.85938,55.10000,23.40000,24.60999,22.75000

1. remember to reconnect the gps antennae in the case that it came off when removing the microsd card.

Also if you want to check the data from the memory card:

datFile = '/Volumes/NO NAME/160818/16081864.DAT'


checkData = function(fpath){

    data = read.csv(fpath, header=F)

    colnames(data) = c('date','time','gpsFix','gpsQuality','latitude','longitude','speed','elev','gpsSat','t_therm','hum_dht22','t_dht22','iramb','irobj')

    data$time = strptime(data$time, format='%H:%M:%OS')

    par(mfrow=c(2,2))
    # temperature of humidiyt sensor
    plot(data$time, data$t_dht22, col="blue", main="temp - dht22")

    # temperature of thermocouple
    plot(data$time, data$t_therm, col="red", main="temp - thermo" )
    # plot ir sensor
    plot(data$time, data$iramb, col="green", main="ir amb")
    plot(data$time, data$irobj, col="purple", main="ir obj ")
    par(mfrow=c(1,1))

}

checkData(datFile);
