4PCS Capacitive Soil Moisture Sensor Module Corrosion Resistant Soil Humidity Detection Module for Arduino Moisture Detection Garden Watering DIY 4pcs

The ALMOCN 4PCS Capacitive Soil Moisture Sensor Module is a popular choice for Arduino enthusiasts looking for a reliable and accurate soil moisture detection module. However, there have been some reported issues with faulty sensors. Some customers reported that all four sensors in their pack did not work due to a known issue with the capacitive soil moisture sensor. They mentioned that if they had researched the problem before purchasing, they would have discovered this issue. One customer compared the ALMOCN sensors to the SEN-13322 sensors and found that the latter provided accurate readings. Despite these problems, customers noted that the ALMOCN sensors have a correct 3.3V timer and an actual voltage regulator. However, this does not compensate for the ground pin problem, which can be fixed with a jumper wire, but is a minor inconvenience when dealing with multiple units. The images in the listing did not reflect the presence of the ground pin problem. Overall, the ALMOCN Capacitive Soil Moisture Sensor Module offers some positive features such as the correct 3.3V timer and voltage regulator. However, the ground pin problem and reports of faulty sensors prevent it from receiving a five-star rating.
