Low Consumption Soil Moisture Temperature Humidity EC PH NPK 7 in 1 Paramete rs 4G Data Logger Soil tester with built-in battery WiFi version is available，It doesn't need simcard it connects Wi-Fi AP in site for Internet access Features 1. Soil parameters measuring Measuring items Parameters Temperature ● Measuring range: -40℃-80℃ ● Accuracy: ±0.5℃ (25℃) ● Long-term stability: ≤0.1%℃/y ● Response time: ≤15s Humidity ● Measuring range: 0-100%RH ● Accuracy: 3% within 0-50%, 5% within 50-100% ● Long-term stability: ≤1%RH/y ● Response time: ≤4s Conductivity (EC) ● Measuring range: 0-20000us/cm ● Accuracy: 0-10000 us/cm range is ±3%; 10000-20000 us/cm range is ±5% ● Long-term stability: ≤1%uS/cm ● Response time: ≤1s PH ● Measuring range: 3-9 PH ● Accuracy: ±0.3PH ● Long-term stability: ≤5%/year ● Response time: ≤10S Nitrogen Phosphorus Potassium ● Measuring range: 1-2999 mg/kg(mg/L) ● Resolution：1 mg/kg(mg/L) ● Response time: ＜1S Important Reminder The measurement of NPK adopts the general rapid detection method, so there are certain error, Use with caution for planting reference. The existing electronic measuring method cannot accurately measure NPK, the error is big, sensor only show trend of NPK. 2. Data logging 128M memory with large logging capacity. Settable data logging interval (1 minute to 24 hour) 3. 4G communication Inside industry 4G module, TCP/IP connect servers via Static IP address or domain(setup by config tool) Communication protocol: CwtIO Settable data uploading interval (1 minute to 24 hour) support sleep mode, automatically wake up when transmit data 4. Low power consumption, Powered by inside battery Inside 8000mA rechargeable lithium battery If data is sent once every 30 minutes, the battery life can reach 1 year. 5. Support solar charging It can be directly connected to a solar panel for power and charging, don’t need solar charging controller. 6. IP68 protection IP68 protection, water and dust proof, it can work outdoors all the time. 7. Support CWT cloud Provide free CWT cloud service, view real-time data on website and APP, support exporting logs Basic specifications System CPU STM32 Working environment -10℃～55℃，5%～95%RH(non-condensing) RTC Update RTC automatically by NTP or manually Memory 128M USB Configuration port, connect PC, provide config software Power External Power supply 12-24V DC Consumption 850 uA when standby, 160 mA when data upload Inside battery 5000mA rechargeable lithium battery Charging Built-in solar charging circuit, directly connect solar panel for charging Options of 4G frequency Option1-EU Option2-AU Option3-A Option4-J LTE-FDD B1/3/5/7 /8/20/28 B1/2/3/4/5 /7/8/28/66 B2/4/12 B1/B3/B8 /B18/B19/B26 LTE-TDD B38/40/41 B40 B41 WCDMA B1/5/8 B1/2/4/5/8 B2/4/5 B1/B6 /B8/B19 GSM/EDGE B3/8 B2/3/5/8 4G working Area Europe, Middle East, Africa, Korea, Thailand, Southeast Asia Australia, New Zealand, Latin America, Taiwan The United States, Canada Japan 4G Communication 4G TCP/IP connect servers, protocol CwtIO Physical Dimension 4g data logger: 146×90×50mm Soil Sensor: 130×45×15mm Weight 440G Protection IP68 Installation screw fixing or Portable Size Provide Config tool
