Operating between 3.3 and 5.5 volts, it features a durable ceramic metal design and a 2.54mm pin spacing for easy integration with Arduino and Gravity I/O shields. Ideal for intelligent agriculture and garden automation, this sensor offers reliable, real-time moisture data to optimize plant care. ## Description Because many people say NE555 does not work, now we have changed to TL555,This analog capacitive soil moisture sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor It is made of a corrosion resistant material giving it a long service life Insert it into soil and impress your friends with the real-time soil moisture data This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V This sensor is compatible 3-pin "Gravity" interface, which can be directly connected to the Gravity I/O expansion shield Review: All Work - Great Product- all them work as expected. Review: Accurate and Not the cheap one - I was able to do a project with these and they worked really well. I did a lot of research on these and I think there are a lot of versions of this product that have some knockoff parts that don’t actually work, but this one seems to be legit! ## Features - Chip is TL555 - Operating Voltage: 3.3 ~ 5.5 VDC - Output Voltage: 0 ~ 3.0 VDC - PH:2.54MM ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SYBSHGX | | Best Sellers Rank | #81,933 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #92 in Soil Meters | | Brand | Songhe | | Brand Name | Songhe | | Customer Reviews | 4.2 out of 5 stars 225 Reviews | | Item Dimensions | 3.86 x 0.91 x 0.39 inches | | Item Weight | 90 Grams | | Item dimensions L x W x H | 3.86 x 0.91 x 0.39 inches | | Manufacturer | Songhe | | Material | Ceramic Metal | | Material Type | Ceramic Metal | | Maximum Supply Voltage | 5.5 Volts (DC) | | Measurement Accuracy | ±15% | | Model | F24 | | Mounting Type | Tabletop | | Output Type | Analog | | Part Number | F24 | | Sensing Distance | 98 Millimeters | | Specific Uses For Product | Intelligent agriculture, Moisture detection, Garden plants | | Style | Modern | | Style Name | Modern | | UPC | 738678030462 | | Upper Temperature Rating | 55 Degrees Celsius | ## Product Details - **Brand:** Songhe - **Item Weight:** 90 Grams - **Item dimensions L x W x H:** 3.86 x 0.91 x 0.39 inches - **Material:** Ceramic Metal - **Style:** Modern ## Images ![Capacitive Soil Moisture Sensor Module Corrosion Resistant Moisture Detection Garden Watering for Arduino DIY 3.3~5.5V 5pcs - Image 1](https://m.media-amazon.com/images/I/71I+61-rohL.jpg) ## Questions & Answers **Q: do you have a library for the arduino? How do I calibrate these? Getting an analog reading does not mean anything..** A: Take a reading while they are dry (that's your 0% reading), then take a sample of your soil and put it in a pot, insert the sensor and then water the pot until it can't hold any more water, then take another reading that's 100% saturated. If you want you can put the sensor near a plant and see what level it reads when the plant looks stressed from to little water and make sure you keep it wetter than that. Note: unless you are measuring pots, the moisture level near the surface is about useless for most plants unless they have very shallow roots.. for plants with deeper roots you probably want to waterproof the top portion of the sensor and bury it about 18" down. **Q: What is the max distance from a pi using 3v3 and using cat5 cable can the sensor be and still work ok?** A: so not sure if you still need this answered or not, but for others it might help. Im using an Arduino 5v, I used about 10 feet of cat5 cable from arduino to sensor. it changed the value some but you just need to calibrate it for that change. example, Arduino to senor without cat 5 = wet "850" / dry "450" arduino to sensor with 10 feet cat 5 = wet "700" /dry "300" **Q: how does this work? do i have to connected to something else?** A: Yes. Depends on what you want to do with it. The output is a voltage value. You can connect to an Adruino type device to display it as analog or convert it to a calibrated digital display of percent moisture. **Q: Will this work (as is) with the Micro:bit?** A: I dont know understand your question. I plugged it into a data port on a esp 8266 read the data using C+ and calibtrated it to meet my needs and transmitted it to a Blynk Control Panel on the internet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ All Work *by M***8 on May 10, 2026* Great Product- all them work as expected. ### ⭐⭐⭐⭐⭐ Accurate and Not the cheap one *by S***Z on December 24, 2024* I was able to do a project with these and they worked really well. I did a lot of research on these and I think there are a lot of versions of this product that have some knockoff parts that don’t actually work, but this one seems to be legit! ### ⭐⭐⭐⭐ Not bad but I don't expect them to last forever *by R***H on March 16, 2022* Have been using these a while, they work well. I'm concerned that they may die from eventual corrosion over time but after all we are shoving a PCB into spil. So far though they worked well for ESPHome and I get fairly accurate readings. Just measure the voltage at 100% saturation of your soil and also read it "dry" before putting into your plant. Has been working well and I'll probably order these again. Tip to the manufacturer: These would be so much better if you had some mounting holes on them. DIY-ers like myself build enclosures and I could easily attach my ESP32 directly to the soil monitor enclsoure that is 3D Printed. Without mounting holes I have to rely on pure pressure to keep the sensor in place. A couple of M3 holes at the top would be a nice addition. So would some solder points so I didnt have to use the cable but not nearly as important. ## Frequently Bought Together - Songhe Capacitive Soil Moisture Sensor Module Corrosion Resistant Moisture Detection Garden Watering for Arduino DIY 3.3~5.5V 5pcs - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/143988194-capacitive-soil-moisture-sensor-module-corrosion-resistant-moisture-detection-garden](https://www.desertcart.pt/products/143988194-capacitive-soil-moisture-sensor-module-corrosion-resistant-moisture-detection-garden) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-10*
