{
“variable”: “bat”,
“value”: “3.134 V”,
“serie”: “1614989279518”
},
{
“variable”: “tempc_ds18b20”,
“value”: “0.00 °C”,
“serie”: “1614989279518”
},
{
“variable”: “conduct_soil”,
“value”: “10200 uS/cm”,
“serie”: “1614989279518”
},
{
“variable”: “temp_soil”,
“value”: “0.01 °C”,
“serie”: “1614989279518”
},
{
“variable”: “water_soil”,
“value”: “32.34 %”,
“serie”: “1614989279518”
