Firstsensor yakagadzira IoT liquid level kuyerwa mhinduro, iyo inoshandiswa pamwe chete neA01 yedu ultrasonic sensor.
Iyo sensor yekuvharisa manhole (ultrasonic liquid level monitoring) inotora tekinoroji yeultrasonic, NB-IOT yekutaurirana tekinoroji uye 2.4G yekutaurirana tekinoroji kuona iyo chaiyo-nguva yekutarisisa yehuwandu hwemvura yematsime ekuongorora.
