ISS Monitor

Announced September 2020, the ISS has activated a 437.800 MHz cross band FM repeater. Using a uplink frequency of 145.990 MHz with an access tone [CTCSS] of 67 Hz and a downlink frequency of 437.800 MHz. This is worth trying so need to know when the ISS was going overhead. Searching for prediction software and come across the Open Notify API which […]

Proposed Activations – 2020

COVID restrictions have placed SOTA and WWFF activations in question. I live in the country so spared the worst of it however have been limited as to where and how far I can travel. Currently the Level 3 restrictions have been lifted. Still have constraints as to visiting people but no longer have to justify leaving home or being concerned […]

Weather Station Update

Weather Station v2 Not happy with the performance of the current external weather station. Whilst it functions as deployed reading reliably the wind, rain, temp etc, is let down by the power demands. This is a flaw with the original design as I can’t exploit low power modes with the inability to determine why the device was woken from sleep […]

Web DB Server

A Linux LAMP server on a ARM processor (64bit Quad Core @ 1.2GHz) in a Raspberry Pi 3. The stack in this case consists of; Linux-raspi2 (5.3.0-1027-raspi2)(Ubuntu 18.04)Apache/2.4.29 10.1.44-MariaDBPHP 7.2 PHP is used to store then display the data. Apache for the heavy lifting. API The REST API is in a simple single PHP file. This is the interface to interact […]

Gateway

Ended up with two gateway devices. This was due to the devices occasionally hanging. A lot of time and debug code was used chasing why they were misbehaving. They just seam to go deaf. The main loop would check if a packet was available then process, …….// else try to parse packetint packetSize = LoRa.parsePacket();if (packetSize) {sendLoRaReceived(packetSize);} so with debug […]

Home Sensors – Software

Surprising how much software is required to support a couple of weather sensors. So the initial list was; Decoding and processing of data transmitted by sensors Gateway device between Lora and Linux DB server Apache PHP API hosted on DB Server Triggers or scheduled jobs in DB Web page for current status Data Storage MySQL Database Rollup / Summarise LoRa […]

Lora Sensors – Hardware

What have I been doing during the coronavirus lockdown, well playing with microcontrollers, This is a continuation of the experiments with Lora devices and have concentrated on developing nodes for measuring basic conditions inside and extended conditions outside. I have ended up with; ASR6501 based internal devices X 2 ESP32 based external Weather station ESP32 based Lora gateway Raspberry Pi 3 […]

Lora Sensors

Sensor Network Have been looking at deploying a sensor network for a while now. Live on land here. My desire is to deploy basic sensors around the block reporting conditions (temp, humidity..) and also to activate relays (water system) or actuators (chicken house door). They will need to be watertight and low power. This is not a surveillance network. Its a […]

Arduino Sensors – Sender

Arduino Sensors – Test Sender This is the code for the test devices based on Arduino UNO. The Duemilanove has hard coded values while the UNO a sensor. This is the code for 1 (Duemilanove with no sensors).  As the sensors come in will be adding to the sketch and simply un commenting the required calls for the target device. […]
