Water-resistant” means that the system protects against water entrance to a degree, but it does notoffer complete protection.
Right now, I'm very interested in low-power, cost-effective wireless devices. What makes it special? As it stands I today already have both a large Zigbee Mesh Network and a large Z-Wave Mesh Network, (as well as six WiFi Mesh Access-Points), and while we also have more home automation products that use other technologies I am a bit reluctant to jump on the bandwagon for a single purpose product that would require me to also maintain many BLE gateways as additional appliances as well. The Tuya Soil Plant Sensor GXM-01 is supported in ZHA too, automatically enabled with a custom quirk: tuya.ts0601_sensor.TuyaSoilSensor. It is correctly identified as an EndDevice with Zigbee Model TS0601 and Manufacturer _TZE200_myd45weu. The sensor can be powered either from two AAA batteries (note that there are externally identical holders but with different pole orientations) or from one CR2032 type element. More recently, the Narrow Band-Internet of Things (NB-IoT) communication technology has been introduced as an emerging technology in the field of WSN [ 128]. NB-IoT has the potential to revolutionize WSN, as it is deployed jointly with existing mobile cellular networks and, thus, enables large-scale and possibly continental coverage in the near future [ 129]. Furthermore, the emerging 5G network is expected to further improve communication and its design and standardization will support NB-IoT applications [ 130]. A wide range of smart applications, including smart farming, are expected to be supported in the near future with high-speed massive connectivity under the same roof of 5G wireless communication [ 131].This review paper presents recent developments in WSN technology for distributed and real-time sensing of soil moisture from the field to the catchment scale and its application in fundamental and applied environmental research. In addition, we also provide an overview of appropriate sensor techniques used in soil moisture WSN applications, as well as a wide range of soil moisture WSN applications, including examples from hydrological research, remote sensing and geophysics, hydrological modeling, and agricultural management. In this way, interested users are given a complete overview of the potential of soil moisture WSN without getting lost in technical details. It has been reported that the communication delay of NB-IoT technology is generally greater than the delay of LoRa due to the complex air interface scheduling process, which also requires iterations [ 56]. This can have a negative effect on the maintenance intervals of IoT devices because a longer transmission time increases power consumption. On the other hand, it has been shown that NB-IoT provides better transmission performance than LoRaWAN in underwater and underground environments [ 57]. The zigbee protocol is a bit different from the BLE in terms of architecture and mechanisms used for communication between nodes.
This Tuya Plant Soil Sensor GXM-01 is officially supported in Zigbee2MQTT and ZHA in Home Assistant. To pair it, install a pair of AA batteries and hold the button on the front for ~5sec until the blue LED starts blinking rapidly. Zigbee2MQTT on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the License Soil moisture data from WSN has also proven to be useful for water balance analysis at the catchment scale. For example, using an empirical orthogonal functional analysis, Graf et al. [ 10] were able to show that two underlying soil moisture patterns explain the overall soil water storage variability in a headwater catchment. Using the same WSN data, Wiekenkamp et al. [ 12] compared the spatiotemporal distribution of soil moisture before and after partial deforestation and found that soil moisture in the deforested area was significantly higher compared with the forested part, especially during the summer period. This, in turn, caused an increase in the frequency of high discharge in the first year after the deforestation. In another study, Wiekenkamp et al. [ 11] used soil moisture sensor response times from a WSN to investigate controls on preferential flow at the catchment scale. They found that the spatial occurrence of preferential flow showed no obvious relationship with spatial attributes, such as topographical and soil physicochemical parameters, but was governed mainly by small-scale soil and biological features and local processes. Metzger et al. [ 76] investigated the influence of throughfall variability on soil moisture variability in a forest stand using data from a dense soil moisture WSN and found that soil hydraulic properties were the dominant drivers for spatial soil moisture patterns. Zooming in the PCB, you can see the Bluetooth Communication Module N52832 [ Datasheet] developed by Nordic Semiconductors, a Norwegian company also supplying the Zigbee module in the Aqara FP1. These modules are also found across SwitchBot’s Product Lineup. This is the most battle-tested and useful firmware. It periodically reads all sensors and broadcast them via Bluetooth Low Energy (BLE). It works with Home Assistant + BTHome out of the box.This is a compact wireless soil moisture sensor, supports working in Zigbee networks. (Zigbee2mqtt open source project, ZHA open source project). The device has an industrial look, at least, I wanted to achieve this. The sensor has very good energy efficiency. Powered by CC2530 chip (Zigbee). The device comes with pre-installed open source software. Much effort is still focused on further optimizing WSN technology, e.g., to optimize data communication to minimize energy consumption [ 123, 124]. In addition, sensor information models such as the OGC Sensor Observation Service [ 125] are being developed to describe WSN data and provide information needed for searching observation locations and sensors [ 126]. This will support the establishment of cyber–physical infrastructures that provide solutions for the integrated management of heterogeneous data resources (e.g., live sensors, sensor models, and simulation systems) and collaborative observation systems based on multiple platforms (e.g., WSN and remote sensing) to more easily provide researchers with relevant geoscientific information [ 127]. If you already own the earlier version of this plant soil sensor [ HHCCJCY01], I see absolutely no reason why you should upgrade to this newer version [ HHCCJCY10]. If you don’t own any plant soil sensors and are looking to get a few, whichever version you can get your hands will work fine. Where to buy?

To measure the temperature of the soil (important in greenhouses) or water, you can solder the DS18B20 in a metal sleeve This data is quite enough to signal the need for watering, as well as, for example, turn on the drip irrigation system in the greenhouse. In Jager's opinion, there is no need to solder on each BME280 sensor, as it is redundant. Version 2I currently do not own any other soil moisture sensors to be able to compare the readings of this Tuya model GXM-01, to prove or disprove their accuracy. Because of this, I can only make assumptions and observations. Even though no clusters are exposed for moisture calibration in Z2M or ZHA, any offset can be easily set by creating a simple template sensor: template: #Calibrate moisture by +5 - sensor: - name: "Moisture Calibration" unit_of_measurement: "%" value_template: " {{ (states('sensor.soil_moisture') | int + 5)}}" Code language: YAML ( yaml ) Verdict
