Aideepen 6PCS Soil Moisture Sensor Hygrometer Module V1.2 Capacitive,Analog Capacitive Soil Moisture Sensor Corrosion Resistant Module Plants

The Aideepen 6PCS Soil Moisture Sensor Hygrometer Module V1.2 Capacitive provides an easy-to-use and programmable option for monitoring soil moisture levels in plants. Compatible with Arduino and compatible clones, this sensor module offers reliable performance and a quick response. However, there have been some concerns regarding the supplied components. Several customers have reported that the photos and circuit diagram provided with the product show the use of a TLC555 timer component, but the actual supplied timer is an NE555. This discrepancy becomes problematic for those using a 3.3V power supply, as the NE555 timer does not have a 3.3V specification. For these customers, the sensor cannot be relied upon for 3.3V usage. This is a well-documented problem with the supply of this type of sensor. While the sensors were found to be compatible with a 3.3V power supply by some users, there are other generic issues associated with this type of sensor. These include a small output voltage difference observed between wet and dry soil and the need for individual calibration of each sensor. With the additional complication of the incorrect timer being supplied, some customers found it too complex to work with. It's worth noting that other suppliers on Amazon do offer this product with the correct TLC555 timer. One customer mentioned finding success with the "ALMOCN 10 PCS Capacitive Soil Moisture Sensor" as an alternative. In terms of delivery and packaging, customers have reported prompt delivery, well-packed items, and no damage upon arrival.
