Battery powered wireless water level switch

Enoki introduces wireless water level switch for paddy field, underground liquid tank level and so on.

The sensor consists of detector, body and wireless module. The body can turn on/off pump.

The wireless module is capable for door bell (315 MHz) and 2.4 GHz (TWE, nRF24L01+, XBee).

It also supports Softbank carrier LTE module sakura.io in Japan.

Detector Key Point
1) Accuracy ±1/4 mm
2) Current loop brings long distance 300m[6]
3) Nearly zero dead zone

Photo22 shows the wireless module on the shovel and the detector in the right.

If water level reaches at desired level or less,

wireless module transmits the event to the receiver.

The wireless module and the receiver is popular wireless door bell.

I tried two door bells and wrote a report for evaluation.

Click the Reports tab in the above menu.

If you set the receiver on your tractor as shown in Photo 23, it tells water level is higher or lower in real time while doing the other job.

I hope that independent or big farmers will adopt Enoki's wireless water switch in the US and so on[1][4].

Crowd funding CAMPFIRE approved to incubate Enoki's small project 'Water level for paddy field' in June 2019[2].

IPROS approved and registered Enoki's product[5].

Fig.1 Enoki's Measurement System

Fig.1 shows Enoki's measurement system. Enoki has tried 2.4 GHz wireless module XBee and TWE since 2015.

The wireless devices are located in the photo 15. #4 is east, #6 and #5 are west, #7 is north.

Each wireless TWE sensor includes a temperature sensor and a illuminance sensor.

Click the below green buttons to see a daily real-time chart on Enoki site or free Xfree site. Chart    Xfree   

#4 was rebuilt to contain #5 as shown in Photo19. So it can measure temperature and illuminance once.[3]

#5 and #7 watch water level. #7 watches water level in the 500 ml PET bottle as shown in Photo 26.

When you shorten between the stake and the probe by sickle or something, the receiver rings a door bell.

This site shows revising manual. Slip21 updates daily record TWE.txt of TWEs in my field all day long in real time.

With mobile phone, you can see the daily real-time chart or report outdoor.

Slip21 also tells alarm by email. If the working PC is Windows xp later, Slip21 can send to free Gmail address or something, though Google browser Chrome doesn't support xp any more. You may receive plain alarm text at enoki.net domain. Enoki offers 1000 trial email addresses for a year now.

Look at Slip21 manual page, and download pre release sample. Try it.

Photo27 Level sensor check by sickle

Enoki tried scheduled FTPS (FTP over SSL) at XFREE. See Reports in detail in 2020.

Enoki have lost 2 XBees in the field test. So Enoki stopped #2 and #3.

Enoki changed #1 XBee module for #2 on 2018-09-13.

After all, all the three XBee EndDevices have broken.

Enoki's rooter often stopped before because of the opened http port and ping. So Enoki has rented Sakura Lite[7].
