Second Range test, about 100m line of sight from Mancave window to back of farm.

Went for a walk with yoghurt pottle containing powerbank at 5v, usb to WeMos mini #1. The receiver ESP8266 was Blue Tacked to window and received packet containing some data from C structure, arbitrary with one int for number of packets sent. The sender at the paddock where window looks out onto sneds packets at rate of about 200ms and blinks each time it receives acknowledge signal from receiver stuck to window above garage. If there was blinking the packets were being sent and received ok. At about 100m the signals were a bit jumpy especially if something was put in front of sender including human body.

Sender code (Arduino, compiled to ESP Arm): https://pastebin.com/aD3pf95z

Receiver Code: (ditto) : https://pastebin.com/1xJhw3fa 

Back against fence. Blinking OK

Spud sensor update 3 August 2022

Image
 Sender WemosI going ok. This is driven by C:\Users\Dell\Documents\Arduino\WorkingOctober22\SpudSensor94H\SpudSensor94H.ino which takes values of temperature and humidity from HDU21 device,with  SparkFun driver, and sends these values to Wemos II, the Listener. Listener's display on serial terminal looking a bit crude but works OK. https://pastebin.com/Fvw5NZbS is the Sender program that reads the HUD21 device and sends info. via espNow to Listener program on WemosII below.. C:\Users\Dell\Documents\Arduino\WorkingOctober22\SpudSensor94H\SpudSensor94H.ino https://pastebin.com/TGdvqSh5 is the Listener program C:\Users\Dell\Documents\Arduino\WorkingAugust22\SantosSensor7\SantosSensor7.ino (NB not ...Sensor6.ino above. Slight improvement. Next task is to tidy up listener code and include semaphore codes that help transfer file chunks from Sensor to Listener. Codes currently are 51 = normal file chunk being delivered from Sensor 59=last fule chunk-ette of extras. (<200 byte...

Real time LDR readings sent to receiver Wemos Mini

Image
 Sent LDR readings to wemos min about 500mm away via ESP Now. The sender uses https://pastebin.com/fKpkv94Y, Sender8 and the receiver uses https://pastebin.com/1xJhw3fa , receiver3with Blink Sender is in the foreground of photo below. Receiver is above metallic pig on window sill. Next put sender with LDR in box or container outside in various positions and check it can send LDR data OK. This would prove the basic outside reading of sensor values to PC inside.
