Practical Application Scenarios
1. Agricultural Wireless Sensor Monitoring System
This E70-900M14S1B module pairs with Ebyte SMT temperature/humidity soil sensor transmitters to build farm-wide wireless monitoring networks. Its 1500m long transmission range covers large open farmlands, ultra-low 2.0uA sleep current extends battery life of field sensors over 2 years, and industrial -40~+85 Celsius temperature tolerance adapts to harsh outdoor farming environments. It transmits soil moisture, PH value and ambient temperature data back to central gateway equipment without wired wiring.
2. Outdoor Security Alarm & Perimeter Detection
Integrate the module into infrared perimeter detectors and fence vibration alarms for residential & industrial park security. The -121dBm high receiving sensitivity ensures stable signal transmission around buildings with mild occlusion; adjustable high air data rate up to 1000kbps supports instant alarm signal upload. Compatible with Ebyte RS485 DTUs to forward alert data to cloud monitoring platforms remotely.
3. Smart Water Conservancy & River Level Monitoring
Deploy E70-900M14S1B on water level gauges, flow meters and water quality sensors distributed along rivers and reservoirs. The wide 2.2-3.8V voltage input fits solar lithium battery power supply systems; Sub-GHz 868/915MHz frequency avoids signal interference from water surface reflection. Engineers can customize firmware to upload periodic hydrological data to industrial control hosts.
4. Industrial Factory Wireless Data Collection
Install the module on production line PLC auxiliary sensors, vibration detectors and temperature transmitters inside manufacturing workshops. GFSK anti-interference modulation resists electromagnetic noise from welding machines and motors; compact 26*16mm SMD size is easy to embed into small-sized industrial sensor terminals. It realizes wireless data exchange between on-site sensing nodes and workshop central control cabinets, replacing cumbersome RS485 wiring.
5. Remote Intelligent Meter Reading (Water/Gas/Electric Meters)
Embedded into residential smart water, gas and electricity meters for remote automatic meter reading projects. The 14dBm stable transmit power guarantees signal penetration through multi-story buildings; low sleep current greatly reduces meter battery power consumption. Support secondary development of communication protocols to match municipal meter reading management platforms, and pass FCC & CE RF certification for overseas city smart grid projects.
FAQ Section
1. Can this E70-900M14S1B module work with 5V TTL MCU directly?
No, its communication logic level is fixed at 3.3V. Direct connection with 5V TTL single-chip microcomputer will cause permanent burnout of internal RF chip. You need to add level conversion circuit (3.3V to 5V transceiver module) to match 5V main control boards.
2. What RF certifications does E70-900M14S1B support for overseas export?
The module has passed CE and FCC standard RF certification, official certification documents can be downloaded on Ebyte official website. It meets mainstream ISM band access standards for North America, Europe and Southeast Asia, supporting commercial OEM export without extra third-party RF test for finished machine in most regions.
3. Is the firmware of CC1312R on E70-900M14S1B customizable for customers?
Yes, the module supports full secondary development. The onboard Cortex-M4F core with large Flash and SRAM allows engineers to rewrite wireless communication protocols, sleep timing logic and data upload rules. Ebyte provides original reference demo code and PCB library files for free to accelerate customer product development.
4. What factors will reduce the actual communication distance from the nominal 1500m?
Actual transmission distance will shrink under conditions including building occlusion, metal barrier blocking, low antenna gain, antenna installation height below 2 meters, high air data rate setting, strong electromagnetic interference environment and rainy/foggy weather.
5. What antenna options are matched with E70-900M14S1B module?
Two official matching antennas are available: TX915-FPC-8521 flexible FPC antenna and TX915-JKS-IPX20 rod IPX antenna. Both antennas match 50 ohm standard impedance of module IPEX port, and can reach the standard 1500m test distance under specified test conditions.
