Description

weight: 485 g

*Note: Joint product & Provided by Banggood and Newchic.

This capacitive soil moisture sensor is distinguished from most resistive sensors on the market and uses capacitive sensing to detect soil moisture. The problem that the resistance sensor is easily corroded is avoided, and its working life is greatly extended.

The sensor has a built-in voltage regulator chip that supports a 3.3 V/5V working environment, which means it works even on a 3.3 V/5V control board. A miniature PC such as the Raspberry Pi only needs an external ADC (analog to digital signal) conversion module to work.
With an external screen and a motherboard, you can talk to your plants! See if it is thirsty and you don't need more water to moisten.
Operating voltage: 3.3 V/5V
Output voltage: 3.3 V/5V
Interface: PH2.54-3P
Size: 98 x 23mm (LxW)

Package Included:

1 x Capacitive Soil Moisture Sensor

ottimo ma attenzione che funziona con almeno 4.5v e non 3.3v. perché monta integrato ne555 che richiede almeno 4.5v

Nice and cheep Product. The LDO is a LM6206, so the max input voltage is 6.5V. The board is based on a TLC555 and outputs a voltage from 3.3V to 0V. It consumes around 4mA at 5V or 3.3V. Wet soil gives a lower voltage than dry soil.

Works fine. I use it with an ESP8266. Be careful: ESP8266 analog input's max. voltage is 1 V! The sensor's max. output voltage is at about 2.8 V.

These are definitely an upgrade to the older fork sensors, and seem to be coated quite well with some sort of epoxy compound to reduce corrosion. The edges of the board, however, are still raw PCB and I would recommend touching them up with some 2 part epoxy before calibration and use, just to extend the life of the part.

not yet tested, product as per website description. some fluxant residue on the solder joints. it looks Ok, satisfied non ancora testato, prodotto come da descrizione del sito web. alcuni residui flussanti sui giunti di saldatura. sembra Ok, soddisfatto

The sensor is based on an a-stable multi vibrator circuit using a 555 where the output duty cycle changes with the sensed capacitance. The simply over an RC circuit integrated signal is the board's output. Unfortunately, the discharge time constant on C (1µF) on this model (Ver. 1.2) seems very high (>10 sec) which is caused by too high valued or non existing discharge resistor. So I simply added a 1.2M resistor from the board's output to ground. There is just enough room at the connector side and already existing via's to easily solder a small 1/10W radial resistor on. This may slightly limit the output swing but gives more stable result voltages.
