AnaSonde-3M Assembly
What is the AnaSonde-3M?
✔ The AnaSonde-3M reads temperature, pressure and
humidity data from the atmosphere.
✔ After the AnaSonde is sent into the atmosphere, it radios the
data back down to a computer on Earth.
✔ The data we receive from the AnaSonde can be plotted and
used to determine the weather in the upper atmosphere,
what type of pressure system exists above the launch site,
etc.

A Quick Lesson on How to Solder
Soldering is the joining of metals by a fusion of alloys
which have relatively low melting points.
Be VERY careful! Soldering iron is HOT!
Tie up your hair! You do not want it hanging
in the way of the hot iron!
Wear Safety Goggles at ALL times! Eye protection is
VERY important!
Do Not Let Solder Bridges Occur!
Make sure you put on enough solder to make the
connection but not so much the circuit is shorted.
Too much solder = Bridges
Too little solder = Holes
Perfect Amount of Solder
No gaps between the board and the part
because there is too little, and no bridges
because there is too much.
Perfect Amount
Let's Begin Assembling Our
AnaSonde-3M!
Install the Socket for U2
Install R1 and R2

It helps to bend the leads of the resistor first before installation and then bending
them a bit again once the resistor is inserted into the holes on the board to keep it
in place.
R1: Blue, Red, Maroon stripes
R2: Red, Red, Orange stripes
After R1 and R2 Installation
Install C1, C2, and C3
✔ You can use alligator clips for
this step to make it easier if
need be.
Install U1
✔ U1 is direction sensitive!
Be certain that the flat edge
matches up with the flat edge
drawn in white on the circuit board.
✔ Also: U1 looks just like the
temperature sensor- Make sure
this is 78LO5 (read the label).
✔Do not mix them up!
Install S1 and D1
✔ D1 is direction sensitive! The longer lead goes into the hole for D1
with the + next to it.
✔ This may be another step made easier by using the alligator clips
to hold D1
✔ Make sure that the switch is in the “off” position at this time.
Install X1 and J1
✔ X1 (the brown package) is not direction sensitive.
✔ J1 is the 4-pin connector. This is direction sensitive!
Make sure that the clip is towards the inside of the board.
✔ There is a little box outline on the board to
show this.
Sensor Installation
Temperature
✔ Match the labels in this picture
with the white labels on the
board.
✔ DON’T push the sensor all of

the way down to the board!
✔ When you are installing the
temperature sensor, be sure
that the individual leads go into
the correct holes on the board.
✔ Make sure that this IS the LM19
package and NOT 78LO5, U1.
Humidity
✔ Like the temperature sensor,
when you are installing the
humidity sensor, be sure that
the individual leads go into
the correct holes on the
board.
✔ Match the labels in this

picture with the white labels
on the board.
+
✔ DON’T push the sensor all of
the way down to the board!
✔ DON'T touch the sensor chip!
Pressure
✔ The pressure sensor has a notch cut
out of pin 1. This pin goes into the
hole with the oval pad on the board.
✔ Once this is matched up, there is only
one way that the sensor will fit into
the holes on the board.
After Sensor Installation
Install U3
✔ U3 is the transmitter. This is direction sensitive!
✔ There is a little notch drawn on the board that should line up with
The circle that sticks out of the transmitter with ND R433 written
on it.
Make sure that this is installed correctly.
Install the Antenna
✔ The antenna is installed into the hole on the end of the
board labeled “ant”.
✔ Bend the antenna so that it sticks straight out from the
board.
Install the 9-volt Battery Snap
The battery snap must have the red lead going to the
positive and the black going to the negative. Thread the
wire up through the bigger holes to the side of the + and
– holes, and then bring them back down through the +
and – holes accordingly.
Install the 9-volt Battery Snap
Install U2 Microcontroller
Test the AnaSonde!
✔ Plug-in a 9-volt battery to the snap and turn the switch to the 'on'
position.
✔ If the LED starts to blink, you're ready to go!
