The circuit is well-documented in the LM393 datasheet’s "window comparator" or "level detector" section.
over time when exposed to moisture and electric current. To extend life, it is recommended to power the sensor only during readings rather than continuously. Applications Automated Irrigation:
Because the probes use exposed metal, electrolysis occurs, causing the sensors to corrode quickly if powered 24/7. yl-105 datasheet
The is an essential tool for any smart gardening project. Its dual analog and digital outputs provide flexibility, while its low cost makes it ideal for multi-point soil monitoring.
The is a popular, compact adapter board designed specifically for the NRF24L01+ 2.4GHz wireless transceiver module . It solves a major issue for makers: the NRF24L01+ operates at 3.3V, but many development boards (like the standard Arduino Uno) operate at 5V. The YL-105 acts as a bridge, allowing users to safely and easily interface the 3.3V wireless module with 5V systems. 1. YL-105 Technical Specifications The circuit is well-documented in the LM393 datasheet’s
Provides a simple HIGH (dry) or LOW (wet) signal when the soil moisture passes a threshold set by the potentiometer.
A compact footprint of 26 x 18.6 x 10mm and a weight of roughly 3g . The is a popular, compact adapter board designed
As moisture accumulates, the sensor's conductivity increases, causing the analog output voltage to decrease (or increase, depending on the module configuration).
The following tables summarize the common technical specifications found in YL-105 related datasheets. Note: Always check the specific manufacturer documentation as specs can vary. Performance Specifications Characteristic Specification 100 psi to 15,000+ psig 1.2.1 Accuracy ±0.5% Full Scale 1.2.1 Non-linearity & Hysteresis ±0.5% Full Scale 1.2.1 Repeatability ±0.1% Full Scale 1.2.1 Output Signal
