Under continuous load applications without external cooling, keep the current demand below 1.5A . Drawing close to 3A causes rapid thermal dissipation across the tiny
Because the HW-133-V1.0 ships with a variable potentiometer, to prevent overvoltage damage. Hw-133-v1.0 Datasheet
| Pin Label | Function | Description | | :--- | :--- | :--- | | | Power Supply | Connect to +5V or +3.3V | | GND | Ground | Connect to system ground | | DO | Digital Output | Low (0V) = Water present / High (VCC) = Dry | | AO | Analog Output | Variable voltage from 0V to VCC based on water coverage | Regulated, step-down DC output voltage (0
The technical specifications of the HW-133 v1.0 make it an excellent choice for a diverse range of applications, especially where a higher voltage source must be efficiently stepped down. and industrial liquid monitoring.
Regulated, step-down DC output voltage (0.8V to 20V).
To retain its low cost and tight geometry, the HW-133-V1.0 omits several safety protections:
Remember to address the corrosion issue with intermittent powering or regular cleaning. With proper handling, the Hw-133-v1.0 provides reliable service for leak detection, gardening automation, and industrial liquid monitoring.
