I-Firstsensor isungule isisombululo sokulinganisa izinga le-IoT liquid, esisetshenziswa ngokuhambisana nenzwa yethu ye-ultrasonic ye-A01.
Inzwa yekhava yomgodi (i-ultrasonic liquid level monitoring) isebenzisa ubuchwepheshe be-ultrasonic, ubuchwepheshe bezokuxhumana be-NB-IOT kanye nobuchwepheshe bokuxhumana be-2.4G ukuze kubonakale ukuqapha kwesikhathi sangempela kwezinga lamanzi lemithombo yokuhlola.
